Starting a new drawing

 To start a new drawing select File > New from the menu  Alternatively use the New drawing button in the standard toolbar  Select List and the system will then display a list of available drawing forms. If the name of the drawing form is known then this could be typed in or used as a wildcard.  Click on the name of the desired drawing form and then use the Insert button.  The system will then display the selected drawing form on the screen and the system is ready to work.  At this stage no name has been specified for the new drawing. The drawing will initially be called UNTITLED until the first time the saves the drawing, at this point the can specify the desired drawing name.  It is possible to work without a drawing form if desired. Simply click the Cancel button. This will allow the to draw/model without the confines of a drawing border.  If at any time the wishes to add/exchange a drawing form, this is achieved by the use of the function Insert > Drawing Form.

3.7

Saving and deleting drawings

 To save a drawing select File > Save from the menu  Alternatively use the Save drawing button in the standard toolbar  If the current drawing is new and has not previously been stored the menu shown opposite will appear.  Simply replace UNTITLED with the desired drawing name, select Type for the location that the drawing should be saved in, and click the Save button.



Please note that drawing names should not contain any blank spaces and giving a drawing the exact same name, as any other object in the Tribon database should always be avoided.

 If the drawing name keyed in already exists in the database the message shown opposite will appear.  Click the OK button and the system will return to the previous menu allowing the definition of a unique drawing name.  If the current drawing has already been saved in the database the system will display the message shown opposite.  Click the Yes button to overwrite the old version of the drawing with the new one.  If you have a drawing open and you wish to save it with a different name use File > Save as. The system will display the menu shown at the top of this page. The current name of the drawing will appear in the Name of drawing field. Edit this to suit and then click the OK button.  Please note that Save as will result in a drawing with the new name being stored in the database, the original drawing will not be automatically deleted.  To delete a drawing from the database use File > Databank > Delete in, the system will display the menu shown opposite.  Select 1 Drawings and the system will display the same menu as when selecting a drawing to open. Locate the drawing to be deleted, using wildcards if required. Click once on the drawing to be deleted and then click the OK button. The system will prompt for confirmation before deleting the drawing. Click the Yes button and the drawing will be removed from the database.

3.8

Functions and operations

When using M3 Drafting we work with functions and operations. Normal use consists of beginning or initiating functions / operations, executing them, then ending or completing in order to make the next operation / function. If we consider the function Insert > Line, this can be started directly from the pull-down menu.  Or started from the geometry toolbar.

 After starting the function Insert > Line we can then start an operation defining what type of line we would like to insert. This operation is started from the toolbar as shown opposite.  To complete an operation or accept a selection, press the Operation Complete Return / Enter = Operation Complete  To exit from a function and quit any operations in progress, press the Quit

Viewports

Viewports (additional windows) can be created, select Viewport > New Viewport stretch a rectangle around the area to be displayed using the left mouse button. A new viewport is now displayed. Floating Viewports can be added using the same method, however they are not restricted by the boundaries of the application, but can be placed anywhere on the desktop. Floating viewports will also have locked within the window the toolbars needed for viewing; the ‘shaded’ toolbar for shaded views and the ‘controls’ and ‘predefined windows’ toolbars for the normal views. Shaded Viewports & Floating Shaded Viewports are also available from the viewport menu. The system will search for a model view in the drawing to shade; if there is more than one model view in the drawing, the system asks the to indicate the view to shade. After the view has been identified, the system will shade the view and enable it by entering shading mode (solid view). As the views are created the system will list them in the Viewport menu, as well as clicking onto the view they can also be made active by selecting them from the list. There are also other options for selecting the viewports:  Next: the next viewport, fixed or floating, will be current  Previous: the previous viewport, fixed or floating, will be current  Cascade: the fixed viewports will be arranged on top of each other  Tile Horizontally: the fixed viewports will be arranged horizontally  Tile Vertically: the fixed viewports will be arranged vertically

Setting up a drawing

3.11.1 New geometry preferences  The preferences for drawing colour, line type, layer and hatch pattern are set under the Format menu.  Select the desired option and the system will display a menu of available options for that setting. Select from the displayed menus by clicking on the desired setting.  When a menu is active and the system is prompting you to select a setting it is possible to use the Options button and indicate an existing geometry. The system will then set the relevant value to that of the geometry selected.

3.11.2 Defaults  To view/edit the defaults for the current drafting session use Format > Defaults.  The system will display a menu containing all the current default settings.  A particular setting can be selected and edited, affecting the current drafting session only.  It is also possible to store the changes made to the defaults but this should not be attempted by a unless with relevant authorisation. The setting and maintenance of the master defaults is considered a task for the elected System Manager.

3.11.3 Drawing scale A Tribon drawing does not have one scale as such instead each view within the drawing has its own scale. As an example of this, main sections, elevations and plan views could be displayed at 1:50 while detail views could be shown at 1:5 or 1:10 etc.  To start a new view with a new drawing scale use Tools > Subpicture > Current  Alternatively use the Current Subpicture button on the Subpicture toolbar.  The system will display the current drawing scale in the message window and display the menu shown.  Click 4 New view and the system will display the following dialogue box:

 The system will automatically display the scale set in the defaults. Modify the scale as required and click the OK button. It is not necessary to type the full string, entering 100 has the same effect as entering 1:100.  The system will redisplay the original menu and the message window will contain information regarding the new drawing scale created. Any geometry created will now appear at the new scale.  If it becomes necessary to add geometry to an existing view it is important to make that view current. Making the view current ensures the correct scale is applied to any additional geometry added to a view.  To make a view current select 1 Existing component from the menu displayed above. Indicate the desired view and select level 1. The various view levels will be discussed later in the course.

29

3.11.4 Title block The creation and maintenance of standard drawing forms for a shipyard is considered a task for the Tribon manager and is therefore covered in the Tribon Managers training course. However after creating these drawing forms the possibility exists to fill in the title block for the drawing via an input form. This ensures all title blocks appear the same as it standardises text style and text height.  To complete the title block via the input form use File > Properties  The system will display the following form.  Fill in the fields relevant to your particular drawing form and click the OK button.  The system will automatically update the fields in the title block with the information submitted in the form.



The type of form to be used can be changed in Format > Defaults. Change the value (1, 2 or 3) for UPDATE_DRAW_INFO_FORM. The default as on the right if for type 1.

Chapter 4 4

Viewing the ship model.

M3 Outfit Drafting allows us to view the Product Information Model database by creating 3D views of the ship model. These views behave like snap shots of the current model, the model objects cannot be edited with drafting but the view can be manipulated to achieve the desired result. This is the basis for creating TRIBON drawings. During this chapter we will be working with an existing model, which has been created, by the designers and modellers at AVEVA Solutions Ltd.. The modelling functions will be covered in later training courses.

4.1

Adding a new model projection to the drawing.

 To create a new model projection or view to a drawing select Insert > Model, or press the button on the standard tool bar.

Or

 The input model dialogue will then appear

How to add model objects

There are 3 main steps to adding a model projection to a drawing. 1. 2.

3.

Select how to add model objects to workspace Collect the type of model objects to add to workspace

Type of objects to select

Name of object, Wildcard search

Define the view to which the collected objects are to be added.

1. First select New as the way to add objects to workspace. NEW

Will create a new view from the selected objects.

ALL

Will add all views in a modelling workspace (CV4) or as a new view.

SINGLE

Will add the objects to a view, selected by the .

MULTIPLE Will add the objects to

multi views selected by the . EXISTING Will add objects to all

existing views

selected objects

2a. Now select Plane as the type of model objects to add. This will ensure that only plane s are selected in the selection process. 2b. Now key in the name of the model object you wish to select, wildcards are accepted. (Note: multiple wild cards may be used separated by a comma e.g. BLOCK1-TT*). 2c. If you are sure about the name that you have entered, press All to automatically select all objects.



Using will display a list of selected objects.

After the system has searched for the requested objects the number collected is displayed. 2d. Press OK when you are ready to add the objects to the workspace/drawing. 3. As it is a new view you will be asked to select a projection for the view. With the cursor, place the new model projection in the workspace. Note that only the first object is displayed at this stage.

32

Number of collected objects

 When placed press objects.

(Operation Complete) to input the rest of the model

 To learn more about creating customised projections see the M3 Drafting, Guide, Model Viewing and General Drafting, Common functions and routines, Select projection.

 The position of the complete View / Subpicture can be moved to an exact position by using a transformation function see chapter 4.20 The model objects will appear in the system designated colours.

As an extra function to using name specification, it is possible to restrict the inclusion of models by means of a defined axis-parallel box in space. All models fulfilling the name specification and also inside or partly inside the box will then be added to the collection.  To select the box restriction, check the Use Box button.  To define the restriction box, click the Def. Box button, and the Box Criteria dialog will show up. In this dialog, the limiting corners (x, y, z) of the box may be keyed-in.

 Another way is to define the box by collecting a number of models. Click the Indicate button and identify the models in the drawing. The coordinates of the box may be presented in different ways, such as absolute, relative to -defined coordinate tables, GENTAB etc. This presentation is controlled by the Coord button.  Any box defined by the may be saved for later access. Just key in the desired name of the box and click the Save button. To retrieve a saved box, key in the name of the box and click Load.  The Restrict Views button controls how to treat the presentation of models collected, but partly outside the restriction box. If checked, parts outside the 2D projection of the restriction box will be removed in the target view.  Another way to add models to the collection is to indicate models in the drawing. Click Indicate button in the Model Selection dialog and collect the models desired.

4.2

How to handle the model objects as a group

As the model objects are added to the workspace together they will remain grouped for convenience. The grouped model objects are in a Subpicture. So to move or delete this we use the Subpicture toolbar.

33

4.2.1



How to delete the Subpicture

 Select the delete Subpicture Icon,

DRAFT_4.2

(also can select Edit > Delete > Subpicture)

 Indicate a part on the View / Subpicture you would like to delete.  Select which objects you would like to delete by choosing a level. If a single subpicture has been identified (level 1 or 3), it will be highlighted but not actually deleted until the confirms it by pressing OC, or by identifying another subpicture to delete. If the selects a level 2 subpicture, the system will search for all subpictures on the same level and with same name as the indicated one and If more than one subpicture with the same name is found, all will be highlighted and the can then select if all or just the one indicated should be deleted.  Subsequent selections of subpictures to delete will then be collected at that level. If the wants to change the level of selection, or invoke other methods of subpicture deletion then select Options and the following dialogue will appear:

By cursor: Will allow the to again select by cursor a subpicture to delete and then the level to delete.

By name: When identifying by name, the system will find all subpictures with the given name on any level and then proceed to highlight them one by one while letting the accept (Yes) or deny (No) the proposed deletion. To delete the remaining subpictures without confirmation, press Options.

Envelope: If a subpicture is temporarily hidden using an envelope, then the can delete a subpicture by selecting the Envelope option. By Area: After specifying the level of subpictures to capture (views, subviews or components), the area is defined by general tools (rectangle or polygon). All subpictures of the selected level and totally inside the area will after confirmation be deleted. To delete the remaining subpictures without confirmation, press Options.



Note that the model data in the database is NOT affected by subpicture deletion

34

Exercise 2  Open the drawing from the previous exercise named ‘DRAFT_EX1’  Input the following plane s: BLOCK1-TTF BLOCK1-TTA BLOCK1-SLOPETT BLOCK1-BHD59U BLOCK1-BHD59L  Choose to add an Isometric View and place this in the lower left of the drawing form  

If the view is too large for the drawing select the scale button from the transformation toolbar, which will appear automatically, and type in 100 (scale 1:100)

 Add the same s using different views to create a drawing similar to that shown below  Save the drawing with the name DRAFT_EX2

4.5

Copy model objects from a view to a view (existing and new)

 To copy the objects from one view to another, select Tools > Model > Copy

 Now select the objects you wish to copy by indicating in a view  To select all objects in a view select level 1. Level 2 will select individual model objects. If 2 is selected, all subsequent selections will be at model (level 2) level.  Press Operation Complete to select all the objects to the memory.  You can then indicate an existing view to copy objects to or press Options to create a new view  Select a projection option; the copied objects will be placed in a new view at the selected projection.  Indicate to place the view in the drawing.  Press Operation Complete to finish.

Exercise 3  Create a new drawing on an A1 drawing form.  Insert a new isometric view of the hull s as per the drawing below. Include all plane s in Block 1  Add all pipes beginning with XX in modules 101* to a separate isometric view.  Copy the pipe objects in this new isometric view to the hull isometric view.  Now copy the resulting pipe/hull isometric view to new section and profile views and position them as shown.  Save your drawing. Try to make your drawing look like the example below. If it doesn't we will learn how to move the views accurately later in the course.  Shade one of the views. If you do not have a shaded viewport open, then open a shaded viewport for one of the views.  If you have enough time, try to create a hidden line views.





38

To Create a Hidden Line View use Tools > Model > Present. Select model part, Choose level 1, Operation complete, Choose Hidden Line, Indicate existing view or Options for new, Yes, Exchange in Drawing, Cancel.

The views are again at a scale of 1:100, therefore you will have to change the scale of the view by selecting the scale button on the transformation toolbar.

4.6

Model draw codes

The detail at which the model is displayed in the workspace can be controlled by the model draw code for example. Low level of detail (Only plate, equipment outline and basic pipe shapes are displayed)

High level of detail (Profiles, equipment detailed volume and all pipe material are now shown)

 To change the model draw codes select Tools > Preferences. Accessing the tree on the right of the property sheet can change the draw codes.  Change the draw codes for ‘’, ‘Pipe’ and ‘Equipment’ as shown:

 We will show the effects of this change in draw code in the next section ‘Exchange model view’.

4.7



Exchange model view.

DRAFT_4.7

As the model is stored on a central database any with access to the modelling systems can modify the objects. This allows work to be carried out by many s in parallel and different areas of the ship to be worked on simultaneously. However in order to preserve version control the views on existing drawings will not automatically change. The model view must be manually updated to see the most up to date objects.  Open drawing DRAFT_4.7  Select Tools > Model View > Exchange  Select a view to exchange (or press ALL)  Select the types of objects you wish to exchange

 Select where the model draw code is to be taken from

39

4.8

Validate

Validate is used to track and optionally exchange all "out-of-date" models in the current drawing. The validation tool will also track and optionally remove all models in the drawing that is not found in the data bank. 

Select Tools > Model View > Validate

The system prompts the to indicate a model view to validate. The can validate all the views in the current drawing by clicking All. A window with a list of possible out-of-date models appears and the can choose what to validate or, if preferred, select All of the models in the list. If the chooses a single item, they then select OK to exchange that model item. A new list appears with the previously selected item removed and the system will await the to select another item to exchange or the they can select All. 

Select Operation Complete to finish.

If there are no models in the indicated view that do not exist in the data bank, the system gives message: 'All models in the model view(s) are valid'

4.9

Creating a symbolic view.

An alternative to creating model views is to create many symbolic views. These can be created to show the model at different intervals depending on the direction of the view (for, aft, port stbd, etc.)

4.9.1

Creating the view

 Start a new drawing using drawing form A1-Aveva  To create a view select Insert > Model then select Create from the Hull View sub-menu  The resulting menu is made up of five separate tabs, Plane, Limits, Select, Outfit and Misc. The Plane Tab Name: Assign a name to the view. The name used should be unique within the drawing.  Key in VIEWFR50



It is important that a name assigned to an existing Tribon object is not used as the name of the view. Therefore never use a drawing name, a name or a block name as the name of a view.

Scale 1: Controls the scale of the text and symbols in the resultant view.



This value does not control the overall scale of the resultant view this should be manipulated by the use of the transform sub-picture function.

Plane X: The resulting view will be a transverse section, typically on a frame. Plane Y: The resulting view will be a longitudinal elevation. Plane Z: The resulting view will be a plan view. 3 Points: The plane of the resulting view will be defined by three points. This option is used to define non-orthogonal views. : The plane of the resulting view will be defined by an existing .

40

Curve: The plane of the resulting view will be defined by an existing hull curve.. RSO: The plane of the resulting view will be defined by an existing Reference Surface Object.



Reference Surface Objects are created in Tribon Initial Design and are used to define compartmentation for the vessel to be used in Naval Architecture Calculations.

 Select X, then key-in FR50 in the window which is now available Looking:



For: Aft: PS: SB: Top: Bot:

The resulting view will look from Aft  Fore The resulting view will look from Fore  Aft The resulting view will look from Starboard  Port The resulting view will look from Port  Starboard The resulting view will look from Bottom  Top The resulting view will look from Top  Bottom

The Tribon default directions for views are as follows: Sections > Looking aft, Plans > Looking down and Elevations > Looking to port. Any subsequent reference in this document, to a Tribon View, assumes these directions have been used.

 Select For Pick: If the current drawing already contains views then it is possible to select one of these and the system will fill out the fields in the form to match those used to create the selected view. After the form has been populated it is possible to change the view name and create a new view using the selected views values. Replace Existing View: If this box is checked the system will replace an existing view instead of creating a new one. If the Pick button has been used the system will automatically replace the view previously selected when the form is submitted. If the Pick button was not used the system will prompt the to select a view to be replaced. The Limits Tab Limits: Defines the extents of the resulting view. If all fields are left blank the resulting view will have the maximum extents. If a plan view (Z plane) or section (X plane) is being created it is possible to click the Portside or Starboard buttons and limit the view to that particular side of the ship. These buttons are not applicable to elevations. The Any button will return the form so the full ship is included in the view, i.e. both Port and Starboard.  Key-in 6000 for maximum Z Depth: Define the depth before and behind the view plane.  Key in 400 for each depth value

The Outfit Tab Select types of outfit items to be included in the view.

The Misc Tab Used to include a co-ordinate axis within the view. Axis position may be selected from the drop down list.

 Co-ordinate axis for section view shown above.  Select Pipe and Equipment,  Select OK

41

4.9.2

Recreate an existing view.

If a view already exists on a drawing it is possible to update it with the very latest model information by recreating it. This instructs the system to interrogate the model and update any changes to objects already in the view and add any new model objects if desired.

1. Use the function Insert > Model then select Recreate from the Hull View sub-menu 2. The system will prompt ‘Indicate view or All’. Either indicate a desired view to recreate or use the All button to recreate all planar views on the drawing.



This option does not deal with views created by ‘3D Pres’, they must be "exchanged " to bring them up to date.

4.9.3

Modify an existing view.

If a view already exists on a drawing it is possible to display the input menus used to create it, modify them, and regenerate the view as required. 1. 2. 3. 4. 5. 6. 7.

Use the function Insert > Model then select Create from the Hull View sub-menu. When the input menu appears, check the Replace existing view box then click the Pick button. The system will then prompt ‘Indicate view’ Indicate the view to be modified. The system will display the first menu again, but this time it will contain the input used to generate the original view. Progress through the menu tabs as detailed earlier, changing all relevant input as required. Select OK when ready.

 The system will regenerate the original view using the modified input data specified.

Introduction to Subpictures

When a model view is created it will display model objects (pipes, s, cableways and equipment) and these in turn will consist of components, (e.g. valves, brackets and plates). Each model view and its component parts will belong to what is called a subpicture. Subpictures consist of up to 3 levels:

  

A VIEW will be created from the input model function. It will consist of a number of SUBVIEWS, one for each model object in the view. The SUBVIEW in turn will be made up of a number of COMPONENTS, one for each part that the model object consists of.

E.g. A drawing can be made up of a number of separate views, each view will be placed at level 1. Each of these views may consist of a number of model objects (e.g. s), each placed at level 2. Each of these model objects may be made up from one or more components (e.g. plates, stiffeners, bkts, etc.), these will be placed at level 3.

4.13

The Drawing Structure Level 2

Level 1 Drawing

Sub-View

Level 3

COMPONENT

Each level of the subpicture can be manipulated as a group; this means they can be moved and edited as one and can be stored and added to drawings as separate entities.

4.13.1 When working with 2D geometry. Subpictures can also be used to group information in 2D drawings. They can consist of up to 3 levels.

Level 2 SUBVIEW: A sub grouping of elements. For example a cabin layout on a deck of similar cabins.

Level 1 VIEW: A grouping of geometric entities - such as a projection for a technical drawing.

Level 3 COMPONENT; Individual elements within the subview. For example an item of furniture in a cabin.

4.14

Current subpicture.

During normal use of the system there will always be a current subpicture. Any new geometry, text, etc., will belong to this current subpicture and its scale will be the set by the subpicture. The Subpicture > Current function controls the current subpicture. The following options are displayed: Existing component

Select (with cursor) an existing subpicture to edit or add to.

New subpicture (auto)

Create a new subpicture dependent on next selection. (level 2 if geometry is indicated, level 3 if a model object is indicated) Will create a new subpicture, the defines the level by indicating the owner. If the owner is at level 2 then level 3 subpicture created and so on. Will create a new level 1 view with a -defined drawing scale.

New subpicture (manual) New view Automatic

Will automatically select a subpicture for new entities, based on the closest entity (next selection) or connected entity i.e. nodes on contour belong to the same subpicture as the contour. This means all geometry drawn will be to the correct scale, i.e. same as subpicture.

The most common use of this function is to make an existing subpicture current so that something can be added to it.

46

4.14.1 Make an existing subpicture current When adding elements, e.g., text, to a drawing containing multiple views, the subpicture with which the elements are to be associated must be selected as the current subpicture before adding the elements.  Select Tools > Subpicture > Current from the menu. or select the Current Subpicture button on the Subpicture toolbar

 Choose option Existing component then indicate an existing subpicture. (cursor position)  View the message line to see status

Transform a subpicture

DRAFT_4.18

The appearance of a Subpicture can be changed using a transformation. These include moving, scaling and rotating. A Subpicture can be transformed on any of its three levels hence the importance of splitting and regrouping (See chapter 4.20).  To transform a Subpicture select Modify > Transform > Subpicture or select

on the Subpicture toolbar

 Select the subpicture to be transformed.  Choose a level using the subpicture level tool bar (or CTRL+ number)

The subpicture is highlighted. It can now simply be dragged to a new position or rotated after pressing Options. All of the transformation options are available (See 4.17.1 Ways to Transform)

 After the subpicture is moved to the desired location press, Operation Complete

4.18.1 Ways to transform. When an entity is selected to transform, the way to transform toolbar will be displayed.

 When using way to transform it is important to look at the message line to see what the system is expecting. It must say 'choose transformation' before way to transform can be used. The most commonly used transformations when laying out symbolic views in a drawing are scale and a combination of Move Two Positions and either Lock U or Lock V, to align the node points of either the base lines or centrelines of two views. Scale: Key in the absolute scale of the Subpicture i.e. key in 25 (Scale = 1 to 25) Select OK. when finished. Move two Positions: Select a point relative to the subpicture, then a new point to where the reference point is to be moved. 1. 2.

Re-use of Subpictures

All subpictures may be stored on a databank and later added to a drawing. They will be stored on the subpicture databank (defined by the logical SBD_PICT). In order to save a particular subpicture, it may be necessary to split a drawing into several subpictures.

4.20.1 To split level 1. (Create new view) Import the dxf drawing CAT.dxf from the C:\Projects\TTP\Draft\ folder. To achieve this select File > Import > DXF, browse to the file and open it, select Load and then select Import.  Select Tools > Subpicture > Split

OR

 Select a subpicture, Choose level 1 as the working level. This means a new level 1 owner will be created.  Select how to Choose geometry from the options: Auto Subordinate Geometry Polygon (CUT) Area (CUT) Set NO CUT

Let the system create a separate owner for each entity selected. Create a new owner for the subordinate (other Subpicture on drawing with lower level) entities selected. Create a new owner for the geometry selected. Create a new owner for the geometry selected by an enclosing polygon/rectangle. Create a new owner for the geometry selected by an enclosing general area Toggle (CUT) feature. If cut is set, geometry intersecting the polygon/general area will be included in the split, if not only the geometry completely inside the polygon/area will be included.

In this case select either a single geometric entity (Geometry) or a group of entities selected by surrounding with a polyline (Polygon) Select the geometry with the cursor or by drawing a polygon around them then confirm the area selected and the split operation. (Options to toggle polygon or rectangle) Polygon to select the geometry to split

The split function will now create a new owner on the working level (in this case 1). So the geometry selected will belong to a new level 1 view.

50

4.20.2 Split level 2 (Create new subview) To create new subviews and components in a subpicture, select a working level of 2 or 3. This will split or move the selected items into a new subview or component respectively.  Select subpicture.  Choose level 2 of subpicture as the working level.  Now select the geometry you wish to move to a new sub-view or component.

  Result new level 2 subpicture.



4.20.3 Regroup Subpicture

DRAFT_4.20.3

This function allows the to move entities from one owner to another. This means entities in 2 separate subpictures can be grouped together. In this case the component from sub-view 2 is moved to subview 1 and thus view 1> sub-view 1 are its new owners.

In this case the component from sub-view 2 has moved to subview 1 and thus it has a new sub-view owner but belongs to the same view.

To regroup two separate level 1 subpictures:  Select Tools > Subpicture > Regroup

Here we want to regroup Section 18-D with the other 18* sections  Select with cursor the subpicture you want to regroup the items to. (The new owner)  Select the level 1, as you want to regroup the other entities as a sub-view to this existing view. Once again there is a multiple-choice menu to determine how the selects geometry to regroup.

Subordinate Neighbour Geometry Polygon (CUT) Area (CUT) Set NO CUT

Move subordinates, indicated by the to another owner. Move all subordinates of neighbours, indicated by the to another owner. Move all geometry indicated by the to another owner. Move all geometry selected by an enclosing polygon/rectangle to another owner. Move all geometry selected by an enclosing general area to another owner. Toggle (CUT) feature. If cut is set, geometry intersecting the polygon/general area will be included in the regroup if not only the geometry completely inside the polygon/area will be included.

 Select Polygon (NO CUT) to allow the whole detail to be selected.  Indicate the geometry you wish to capture (see below left).

 Press operation complete then Yes to accept the regrouping. The selected subpicture will now be a subordinate (in this case a level 2 subview) of the owner subpicture (see above right).

Dimensioning

Measurements are divided into the following main categories: Linear, Radius, Diameter, Angle, Curved Length, Area, Distance From a Plane, and 3D rulers The dimensioning functions make use of a variety of parameters that control the layout of the resulting measurements. When starting up a session, all these parameters are initialised from the application default file. The layout parameter settings of the Linear, Angle, Radius and Diameter measurements do not normally influence each other. However, the Co-ordinate, Curve Length and Area measurements share relevant layout parameters with the Linear set. 2D dimensioning is activated from the Dimension menu or the dimension toolbar.

Basic geometry

When we have a model view on the drawing we can add 2D entities, such as dimensions details and notes to provide more information about the model. Creating 2D geometry will not only provide further annotation to the drawing, but can be used to help in creation of modelling objects. Rectangles or polylines for Structure plate definition, or general primitives in volume creation, construction lines used to make pipe routing easier. This chapter will introduce these basic drawing and annotating functions.

6.1

Creating geometry

6.1.1

Points

Points in drawings are represented as a small cross. The actual need to display a point and see the cross on a drawing plot is not very common; therefore we seldom actually create points in a drawing. However, points are used extensively when creating/positioning geometry. To avoid the need to have these small crosses all over the drawing, a particular point type can be selected and after an indication in the drawing, the system will create a temporary point allowing the creation of basic geometry. Cursor point. A point at the cursor position when the mouse is clicked. Node point. A point at the closest end point of an entity. Key in co-ordinates of a point. A point specified by u,v co-ordinates.

Event point. When in drawing mode will be at closest connection point. Midpoint. A point at the closest midpoint of entity. Intersection point. A point at the closest intersection of two entities. Nearest point. A point at the nearest part of the nearest entity Existing point. A point at the nearest existing point on the drawing Centre of Arc. A point at the centre of the closest arc Arc by angle. A point on the closest arc at an angle specified. (0 at horizontal and +ve anti clockwise) Distance along a Contour. A point at a specified distance along an entity. Distance taken from end closest to indication of entity. Centre of Gravity. A point at the centre of area of an enclosed contour. Symbol connection. A point at the closest symbol connection point.

Offset current point. A point offset by (∆u, ∆v) from the current point. Automatic point. A point at the closest node, midpoint, intersection, etc. as defined by the .

69

Add offset. A point offset from the next point defined. (the next point defined will use the point mode selected before the Add offset mode).  To actually add a point to a drawing, use Insert > Point.  Alternatively use the Point button on the geometry toolbar. Select the particular point definition required from the 2D Point mode toolbar or by using the mouse right-click 2D point option as indicated. The image below shows examples of the various point types:

When either adding a point, creating geometry or using the point mode for selection purposes the system indicates a position it recognises that meets the current selection (cursor, node, midpoint, etc). The cursor is shown as a small circle to indicate this location. Node Point

6.10.2 Ways to transform.

DRAFT_6.10.2

Within the Tribon system there are many possibilities to move geometry a specific distance or rotate it a specified angle. When an entity is selected to transform, the way to transform toolbar will also appear.

 When using way to transform it is important to look at the message line to see what the system is expecting. It must say 'choose transformation' before way to transform can be used. The above toolbar provides the following functionality: Scale: Key in the absolute scale of the Subpicture i.e. 1:1 (Key in 1). Options will allow the to give a relative value (i.e. 0.5 will double the size of the entity and 2 will half the size of the entity) Move delta: Key in an offset (U,V) relative horizontal and vertical components, e.g. X, Y in plan view drawing.

Move two Positions: Select a point relative to the Subpicture, then a new point to where the reference point is to be moved. 1. 2.

Select a reference point relative to the Subpicture, Then a new point where the reference point is to move.

Volumes

Volumes are 3D forms, which are modelled by the to create a representation of an outfitting item. They can be positioned directly in the ship model as PLACED VOLUMES or they can be associated with a component and thus placed as EQUIPMENT. The volumes are created on General Volumes Databank with unique name. Each item must have a unique name so it can then be stored on the General Volumes Databank (SBE_GENEVOLDB) that can be accessed from all projects to save rework. They are modelled by combining a number of volume primitives. Primitives are simple 3 dimensional forms created by providing a few simple parameters. Combining them allows the to create complex and realistic volumes easily and quickly.

Tribon volumes allow the to model volumes using 2D and 3D functionality by using 4 views simultaneously. This means modelling in the principal planes is very simple.

Connection points - Connection points for cable, pipe and ventilation connection can be defined anywhere on the volume. There can be 199 per volume and each will have an X, Y, Z location (relative to the origin) a vector and a descriptive string

103

Density and softness - Each primitive can be assigned a density and softness. The density can be used to estimate weight and COG of the volume. The softness will provide information for collision control calculations. For example: Softness

Result of collision

0

Direct collision with equipment/hard collision

1

Service Area collision/soft collision.

2

Example Volume

Dismantling space/soft collision

3

Maintenance space collision / soft collision

4

Insulation Area collision / soft collision

 Subvolumes can be used to reduce rework. Groups of primitives can be stored as sub volumes these can in turn be imported into any other volume on the databank. Common uses of subvolumes are small common assemblies used in pipe equipment, complex volumes that make up larger accommodation modules.

Input primitive (3D-polygon - 2D mode)

This primitive is a polyline in 3D space, it is created by defining a series of 3D points or by locking on of the 4 views and working in one plane at a time hence 2D functions.  Select the 3D polygon from the primitive menu.

 Choose 2D mode (This allows working in one view as a normal polyline)



By default the XZ view is used to define the polyline. This can be changed with Switch View.

 Draw a polyline as normal in the XZ view.

 The result will be a polyline on one plane in 3D space.

8.20

How to define a 3D point

3D points are required to define the route of 3D polyline primitive, pipelines and cableways. They can also be used to place equipments. Here is the simplest way to define a 3D point:  Enter a 3D function, i.e. route a 3D polyline in 3D mode  Select cursor position and indicate a point in a view

122

rd

 A locking line will appear on the 3 remaining views.



Indicate a point on these locking lines to collect the 3 co-ordinate, which is locked to this axis

The fully defined 3D point will be shown by a circle in the highlight colour. This is now the current point

8.20.1 3D Request menu A 3D point can also be defined by making a 3D Request, this allows us to snap to a 3D point, in a similar way to the point menu for 2D points. It can be accessed in 3D functions from the point menu  The 3D Request menu

 The 3 modes of selecting a 3D point  KEY IN This mode prompts the to key in the coordinates (x,y,z) of the point. To return to the 3Drequest menu, press return or select Cancel.

 EVENT mode requests a 3D-event point (connection points, ends and midpoints of components) or a point defined by a combination of 2D points.

Defining a 3D point with a combination of 2D points  OFFSET CURRENT. If a current point is set (indicated by the circle) we can define the next 3D point as an Offset from this Current point (dx,dy,dz)

123

8.20.2 Locking Commands (lock plane)

These sub-functions will lock an arbitrary plane chosen from the menu.  LOCK VIEW will lock a plane, ing through the current point, defined by a projection (view) in the workspace. From the current point the will select a view to lock (e.g. plan view) and that view is locked for direction Z, only allowing definition in X and Y directions (locked plane).

 LOCK EVENT PLANE will lock a plane perpendicular to an event point vector and at that point. From the current point the indicates an event point and the system creates a locked perpendicular event point creating the locked plane. Selecting the next point on the locked plane will produce the required result. Perpendicular event point

Locked plane

Current point  LOCK X, Y, Z will lock the current value of X,Y or Z, therefore only allowing definition in the other 2 axis, dependant on option selected, creating a locked plane at the current point.

Lock X

The 3D point defined (using EVENT

(cursor point)

or OFFSET CURRENT) will be on this locked plane.

Most of the locking subfunctions require that the current point is set.

124

8.20.3 Locking Commands (lock line, define direction)

These sub-functions will lock an arbitrary line chosen by the or from the menu.  LOCK EVENT LINE: desired event point.

Lock V A line ing through the current point and a second 3D point. The defines the second

Event point

Locked event line

Current point

125

 LOCK YZ, XZ, XY in the X, Y, Z directions

will lock the current value of Y and Z, X and Z or X and Y therefore locking an axis

Direction Y (Lock XZ)

The 3D point defined (using EVENT (cursor point) or OFFSET CURRENT) will be on this locked line. Most of the locking sub-functions require that the current point is set.

8.20.4 Other 3D request Commands

 ADD OFFSET from a 3D point. The point to add offset from is selected by using, key in or Event points. The 3D-point mode must be selected before ADD OFFSET is selected. (NB this is the same as setting a current point then adding an offset current)  allows step-by-step definition of a 3D point. The defines a 3D point, the system verifies the point and asks the if the point is to be accepted. If the answer is yes the definition is complete. If the answer is no, the system lets the define another 3D point and then type in the relevant co-ordinates (XYZ)  UNLOCK

unlocks any locking line or plane.

 SET CURRENT

sets a current point for adding offset or locking an axis. Offset Current 0, 200, 0

Set Current

 Select New from the volume menu. Key in the maximum dimensions of the volume, 2000  Select Volume > Primitive > Insert, then select the 3D polyline primitive  Select 3-D mode to allow 3D requests

To start at the origin we will use the node points as reference  Select node point from the point menu.  Then indicate the axis reference as the start position.

Indicate in another view to fully define the 3D point.

127

 A circle will indicate the current point (in this case the start position). An 'elastic' line will be attached to the current point in the default view.

 Lock X so we can route the polyline on the ZY plane.

Use 3D request to change the MODE from EVENT to Offset Current  Now we can add an off set from the current point in the locked plane. Key in the following offsets to achieve the first three segments of the example.

 To create a segment on Y-axis that goes to Y = 0 we can utilise the locking functions. To exit the offset current mode  press

Options or OK with a blank line

 Change the point selection mode to EVENT. (This will allow a 2D node point o be chosen.)

128

 Then select Lock XZ

from the 3D request toolbar, so the segment will only extend along the Y axis.

 Now the node at the origin can be selected to capture the Y co-ordinate from.

 To define the final point, which will close the polyline, we can key-in the origin position as the last 3D point. Select Unlock then Keyin from the 3D request tool bar.  Then simply key in the co-ordinates of the final point, 0,0,0  Select Operation Complete to finish the polyline

8.22

Softness and material alias. (Demonstration)

A material alias will refer to softness, as defined in a default file with Logical SB_MTRL_ALIAS. Softness is a variable set for primitives when creating a volume. The material alias is used to set different conditions for collision control. A default file for Drafting is created to assign material alias. This file is stored in the def directory usually with the name SB_MTRL_ALIAS.def, the file is a simple text file. Example:

To create this Generator with a maintenance space defined:  Open the original volume MAN_6L16-100  Add new primitives to represent the maintenance space (shown in red)  Use Volume > Softness > Modify to change the softness of the new primitives to 3 (=maintenance space as in default file above)  Store modified volume with new name MAN_6L16-100-M (this must be different from original volume to allow different detail level in component)

To create dismantling space for Generator:  Open the original volume MAN_6L16-100  Add new primitives and set the softness to 2 (=dismantling space in default file)  Store modified volume with new name MAN_6L16-100-D

Chapter 9 9

Components

The component concept is a central part of Tribon outfitting applications. A component is a standard material item, which can be used many times throughout a ship. Components are stored in the Component Repository (gcdb). Every component has a unique name and is classified into main classes, such as piping components, electric components etc. There is further subdivision in the component families down to the level of type 1 and type 2 penetrations. This classification is known as Type description. Each component has a type code associated with its type description, and each type of component has unique characteristics. A lot of information of different kinds can be defined and stored for one component. The data is divided into blocks e.g. graphical block, piping property block and connection block. These blocks can be mixed depending on the kind of component. For each component type a certain set of component blocks is used. It is not necessary to define the complete component from the beginning, as it is always possible to add more information gradually. It is also possible to update/change information that already is defined and stored.

9.1

The Component Maintenance Program

The component information is stored in component objects in the Component Repository. This databank can be accessed, and component objects created, ed to and updated by using the M3 Component Maintenance program. M3 Component Maintenance has two main functions:  To search for existing components to view the data.  To update the databank, with new components or changes to existing components. The component maintenance application takes the form of a browsable tree, which works in the same way as Windows Explorer. The component blocks can be viewed by double clicking the component or right clicking then selecting properties. Main Class Class Sub Class Family

2D representation

DRAFT_9.1.1.7

Symbol representation: Equipment items often need to be represented in system diagrams for piping and cabling. A symbolic representation is most commonly used. Each component can reference Visio Stencils and Shapes so that the correct symbol is always used when that component is used in a diagram.

Symbol Usage Code: 1 = Pipe Diagram 4 = Pipe Modelling 5 = Isogen Modelling 21 = Electric Circuit Diagram 22 = Cable Diagram 2D Subpicture representation: Equipment items often have to be shown on drawings such as General Arrangements where the full 3D detail is often not required. Therefore we can also use a 2D subpicture to represent the component. Projection Properties: Field Direction Name Usage code Detail level

Description Projection direction vector. Name of the sub-picture. Usage code for the projection (see above) Detail level of the projection.

Volume Representation

Subpicture Representation (Elevation to Port view =V)

138

A subpicture is saved on the SBD_STD databank. It is referenced in the Proj page of the component. The Direction is given according to the view that it will be used in (in this case V is chosen – elevation looking to port)

Use Tools > Preferences > Miscellaneous to influence the type of representation.

139

9.1.1.8

3D representation.

In order for equipment items to be represented in 3D the component used must refer to a volume. More than one volume can be referenced by the component, which can be utilised for different detail levels and collision control. Volume usage code: 2 = Pipe Modelling 4 = Pipe default volume 6 = Insulation default volume 11 = General equipment placing 30 = Structure misc. component volume 1 31 = Structure misc. component volume 2 90 = Structure general cross section For an equipment the: Volume type is always = 2 The usage code is 11 Scale factor should be = 1 And detail level is defined.



9.1.1.9

(In Tribon M3 Outfit Drafting, and other modelling applications the may choose between different detail levels, Using model draw code)

Other Information Extensions Here the can specify the maximum and minimum extents of the component representation. This is not required if a volume is referenced The centre of gravity, the weight as defined in General Information; to act through is defined here by the U, V, W co-ordinates relative to the origin of the volume used.

Component references A component may refer to other components, e.g. pipe flange with bolts and gaskets. These components can be referred to here

defined info. If the wishes to add more data to the component (which can be listed at a later stage) it can be done so here. Column 1 for integers Column 2 for real values Column 3 for alphanumeric strings

140

ed Attributes If the components are ed from Tribon.com then the attributes they are given in the Global Database, will be ed with them and are then visible in the maintenance programme. System Data (technical information), and Event Data, such as broadcast and published dates are listed. No Tribon information appears on the ed Attributes block.

Attachments If the ed components have attachments (drawings, tech., documents, logos, etc.), then these items will be ed and viewed using Tribon viewer software.

9.1.2

Naming Components

Components are named, as the requires. The following characters are allowed in component names: -.1234567890ABCDEFGHIJKLMNOPQRSTUVWXYZ

9.1.2.1

Components Groups/Single Components

The components can either be a member of a component group or it can be a single component. Whether it is a single or group component is specified when the component is created.

9.1.2.2

Component Group Member

The component name consists of a group name and an item number within the group: - The group name can contain any characters (also -) but the item number must be an integer. Therefore the last ‘-‘ in the whole name will separate the group name from the item number. Examples: F47-3, FUSE –12-4

9.1.2.3

Single Component

The components can have an arbitrary name which can include the character ‘ - ‘



At the moment, Tribon.com does not have any Group Member functionality; therefore every component is ed as a Single Component.

9.2

Creating Components

There are, at the moment, two main ways of adding components to the Component Repository in Tribon M3. It is also possible to import components into the maintenance programme using the application Components from File (su016.exe); this will be covered in the M3 Tribon Outfit Manager course. The main two ways to add components are:  ing Components from Tribon.com  Creating component interactively in the Component Maintenance programme

ing Components from Tribon.com

Tribon.com is a powerful web based application designed to the integration of Supplier Information into the customers Design Systems, and assist in the Procurement phase in Shipbuilding. It allows the to search the Global Database (GCDB) for suppliers and products that match desired technical requirements and then selected components into the local component database (LCDB). The components can then be used directly in the Tribon Product Information Model (PIM). E-Commerce functionality is provided to enable the to request information and quotations from suppliers, initiate reverse auctions and create purchase orders.

Equipment.

Equipment’s are outfitting items that are placed as one instance of a component in the ship model. They are stored as a unique object on the General Equipment databank (SBE_GENEQPDB). Equipment’s refer to a component for technical and graphical information and additionally store production and design data. Equipment’s can be created by:  Updating an equipment object with the Equipment Maintenance program.  Using the equipment maintenance program via General Diagrams.  Interactively placing the equipment from Drafting or other interactive applications.

10.1

Equipment maintenance.

The equipment information is stored as equipment objects in the General Equipment Data Bank (SBE_GENEQPDB). This databank can be accessed directly and equipment objects created or updated by using the equipment maintenance program. Equipment maintenance has two main functions:  To search for existing equipments to view the data  To update the databank, with new equipments or changes to existing components. The equipments are displayed as nodes of a tree, the Project being at the top and each Equipment Module (area on ship) being displayed as a node.

Using Material Alias with Collision Control

To allow for soft collisions based on material aliases we must first ensure the component has the correct information defined. Assuming the relevant volumes have been modelled (see section 8.22) they must be assigned in a component. Different detail levels are used to control which volume is used.  Start the component maintenance programme (TribonM3 > Outfitting > Components)  Locate and select component MAN6L16100  Select the Volume tab. The volume MAN_6L16-100 is visible showing the parameters for that volume

 Add a second volume (MAN_6L16-100-M) to the component, making the detail level 5

 Add a third volume (MAN_6L16-100-D), this time the detail level should be 4

It is good practice to decide upon a convention for detail levels and their respective meaning: 9 = full detail level 5 = full detail volume with maintenance space 4 = full detail volume with dismantling space 1 = simplified volume for preliminary layout

185

To utilise the volumes with service area and dismantling space we must use the model draw code to toggle between the different representations defined for the component.  Open drawing DRAFT_11  To change the detail level of equipments, select Tools > Preferences  Open Model Draw Code and select Equipment  Select Level and then change the value to 5

 Use Tools > Model View > Exchange to change the presentation for the Equipment which will show the volume with the maintenance primitives

 Select Tools > Model > Collision Control  Perform the collision check for the whole view (level 1)  When system returns with collision status, choose option 3 Highlight one by one  The system will show the collision and also report in the message window the models that are colliding, and the type of collision

 Repeat the same process to check collisions for the volume for dismantling area: 1. 2. 3.

Change the model draw code for Equipment to detail level 4 Exchange the view to show the equipment with dismantling primitive Run the collision control for the view (level 1)

Appendices

12.1

Appendices 1 (Collision Detection)

In Tribon M3, Collision Control can be used to detect, review and approve collisions between different models in a design. The tools are both available in Design Manager and Drafting based applications, however the interfaces, especially in the selection of models process, are slightly different. The following will show the ways of working for Drafting based applications. In Drafting based applications tools are to be found in the Tools > Collision Control menu or in a separate toolbar. The models are selected by 2 possible options: 1.

Keying in or retrieving the model names in the Insert Model selection form

2.

Indicating models in drawing through the Indicate button in the selection form. When the indicate option is selected the will have to choose the level for collision, view or sub-view.

Whichever option is chosen the system will show the model items collected. Select OK when the correct items are chosen and then select OK again to initiate the Collision Viewport and report window. Dependant on the type of collision process selected the parts chosen and reports will differ.

12.1.1 Collide Collide calculates and reports all collisions between selected models. Normally this function would be used to check a specific area of the model. To use this function select Collide from the Collision Control menu, collect the models through the various methods, and when complete the application will open a viewport reporting the collisions. If level 1 (view) was selected through the indicate option then the report will show collisions for the view, however if the level 2 (sub-view) was indicated then more than one level 2 would have to be selected. If the key-in method was used for collection then more than one model item would need to be collected.

12.1.2 Collide Selected Collide selected calculates the collisions between the selected model and the rest of the models in the design. Models from all disciplines are included in the calculations. To use this function select Collide Selected from the Collision Control menu, collect the models through the various methods, and when complete the application will open a viewport reporting the collisions. Normally for this option the selection of individual model or model items is preferred as the nature of the function is to check individual objects with the rest of the project.

12.1.3 Collide within Box Collide within Box calculates an axis-aligned box around the selected model and then reports all collisions within the resulting box. To use this function select Collide within Box from the Collision Control menu, collect the models through the various methods, and when complete the application will open a viewport reporting the collisions. As for Collide the quantity of objects selected will determine the collision report.

12.1.4 Clearance Distance This tool is used to specify a clearance distance around a selected model. Distances between 0 and 500 can be specified and a zero distance can be given to disable clearance check for a model. Clearance distances are ed and used each time a collision check is made. Clearance violations are reported as collisions of type Parts too close in the collision list. Select Clearance Distance from the Collision Control menu, collect the model required through the various methods, and when complete the system will present the following dialogue for the input of the clearance distance.

187

12.1.5 Collision Reporting and Approval The presentation of collisions is made in a list window and in a graphical view.

12.1.5.1

Collision Report Window

Collisions reported by the collision detecting tools are listed in a specific list window that contains the following columns:



The First Part - The name of one of the colliding parts



The Second Part - The name of the other colliding part



Collision Type - Type of collision, the following types are defined: Collision Parts too close (clearance violation) Soft collision



Detection Date - Date when the collision was detected the first time



Distance - Shortest distance between the two parts, used for parts colliding within the clearance distance



Approval State - The following approval states are defined: Not approved Approved Modified after approval. The colliding parts have been modified after approval.



Approved by - Approval signature



Approval Date - Date for approval



Approval Reason - The following approval reasons are defined: None False collision. Collision caused by an inaccurate geometric representation of the model.



Remark - Remark that can be given when a collision is approved.

All columns can be sorted by clicking on the column headers. Detected collisions or collision approvals are not immediately reflected in the database, it's first when the collision report window is updated by new collision reports or when the application is terminated. The can explicitly store updated item in the database by pressing the Save button. The environment variable SBB_COLMGMT refers to the database for storage of the updated items.

188

The listed collisions can also be saved to a file by pressing the button Export to File.

Approved collision reports can be removed from the list by pressing the button Hide Approved and showed again by pressing the same button a second time. Also when the selects Collide, Collide Selected or Collide within Box to perform collision checks in the future, all of the relevant updated collision data will be retrieved to the report window.

12.1.5.2

Graphical Presentation of Collisions

Colliding parts can be presented in the graphical view by selecting the corresponding collision report in the collision report window.

An efficient way to present the surroundings to a collision is to use the Show Surrounding Models command. This command can be found in the right click menu for the graphical view's background.

189

12.1.5.3
