Exercise 1 – Creating a Drawing

4.12 Modify an Existing Symbolic View

4.12.1 Modify the view

Selecting Symbolic View > Planar Hull View > Modify from the application pull-down menu opens a Multiple Choice form to modify views

1. Remake panel will update the panel from the model.

2. Add reflected image will produce a reflected image of the panel selected.

3. Add named panel allows a named panel to be added to a view.

Amending the limits from the Create View form can modify the limits of a view. However the limits can also be modified interactively by indicating the desired limits on the screen.

4. Modify limits

 Select Symbolic View > Planar Hull View > Modify.

 Select option 4 Modify limits. The system will prompt ‘Indicate view‟

 Indicate the view that you wish to modify. (A rectangle will be drawn around the view).

 If the view with the rectangle is the one you wish to modify click Yes on the displayed dialogue box.

 The system will prompt ‘First cp‟. Indicate the first corner of the desired limits.

 The system will prompt ‘Next cp’. Indicate the second corner of the desired limits.

 The system will create a rectangle from the two indications and redisplay the OK? prompt.

 Click Yes if happy with the rectangle. The system will return to the original multiple choice menu.

 Click Cancel to exit the function.

5. Restrict, contour will restrict a view by a pre set contour. (Created with geometry) 6. Restrict, line restrict a view by a line defined by the user.

7. Copy Restrict takes a copy of the restricted view

4.13 Detail Views.

As well as creating all the required views for the generation of panels, and the creation of drawings, the system can also produce detailed views of existing Flanges, Stiffeners, Brackets and Seams.

As well as specific functions for the objects previously mentioned, there is also the Two cp‟s option, which allows a quick view to be generated anywhere in the ship to help visualise the 3D model.

4.13.1 Creating a Detail View of Multiple Objects.

Select Symbolic View > Planar Hull View > Detail… from the application pull-down menu.

If a detail view is required for several objects then the Two cp‟s option should be used. This allows the user to define a view plane, define the direction of the view and also define the extent of the view.

Select option 1. Two cp‟s

The system will prompt ‘Cursor position’.

In the example shown a view in way of the fwd CL, there is a requirement to see the supporting structure for clarification of detail.

Indicate two cursor positions as shown below.

The system will join the two-cursor positions with a line and display a prompt, if the line is correct click OK The Create View menu will appear, make all the desired selections to include/exclude panels, blocks, curves in the view or change any limits etc.

Alternatively just click the OK button on the menu and the system will automatically display all relevant objects in the detail view.

The system will now generate the view and request the user to position it on the drawing. The view in this case will appear as shown below:

4.13.2 Creating a Detail View of Flanges, Stiffeners, Brackets or Seams

Select Symbolic View > Planar Hull View > Detail… from the application pull-down menu.

Select either: 2, 3, 4 or 5 to suit the object that you wish to make a detail of.

The system will prompt „Identify‟ for Flanges, Stiffeners and Brackets or „Indicate Seam‟ for Seams.

Indicate the specific object you want detailed.

The system will now produce a detail view of the object selected.

Indicate a position on the drawing to place the view.



For details of Plate Edges you must have the Extended Bevel handling option. When indicating

stiffeners do so in a plane view not a section view. If a detail of a particular end of a stiffener is required indicate near that end. If a detail of a whole stiffener is required indicate in the middle third of the stiffener.

4.14 Model Information

The model objects in the workspace are not only 3D representative but they also contain other production and assembly information

Select Tools > Inquiry > Model from the application pull-down menu or click the Model Information button from the File toolbar

Select the model part to be queried.



This function can only be applied to Hull elements. It is expected that Outfitting elements can be queried using the common attribute forms.



Refer to Appendix A for use of the Attribute forms.

4.14.1.1 Navigate to Position in Explorer

Select the model component in the drawing, right click on it and select the Navigate option from the context sensitive menu. The choices of in Design Explore, in Draft Explorer or in Drawing Explorer are available.

The component selected is highlighted in the relevant explorer.

Exercise 2 – View Creation

1. Start a new drawing using an A1-AVEVA drawing form.

2. Create an isometric view of BLOCK F401. Scale 1:75

3. Create an isometric view of ZONE 403-PIPE belonging to SITE PIPE-4DK_FWD. Scale 1:75.



Unless stated for all Views containing Outfitting elements use the Universal Hidden Line and /TT/DRA/PRJ/REPR/GEN/BASIC for View Type and Style respectively.

4. Create a symbolic view at FR160 looking aft using the following limits, Z max = 3600. Scale 1:75

5. Add a detail view at section using two c.p.‟s from the first girder to port. Scale 1:75.

Use the limits X min FR158-200 X max FR162+200, Z min 0 Zmax 10000.

6. Create a stiffener detail from one of the stiffeners on FR 160. Scale 1:25

4.15 Adding Rulers to an Existing View

When a project is set up in AVEVA Marine a number of tables are created in the background. Some of these tables contain the co-ordinates of the Frames and Longitudinal positions for the ship. Therefore it is possible to add a centreline, baseline, frame ruler, longitudinal ruler, etc to any symbolic or model view created on a principle plane.

1. Use the function Annotate > Position Ruler from the application pull-down menu.

2. The system will prompt „Indicate model view‟. Click on the view.

3. The system will highlight the view selected and display the 3D Ruler form:



Only the relevant rulers for the view selected will be available, other rulers will be greyed out.

4. Select the ruler to be added to the view and the system will prompt ‘Locate ruler’.

5. Click once in the drawing to position the ruler. The system will now prompt ‘Trim ruler by cursor position’.

If required adjust the extent of the ruler by indicating on the screen. If extent is OK then click the OC button.

6. The system will now redisplay the 3D Ruler form again.

Either add another ruler to the same view or use the Cancel button if no more rulers are required in the active view.



When adding a Frame Ruler the user can click the OC button to automatically position the ruler at the CL or BL depending on the view projection.

7. The system will prompt „Indicate model view‟. Either indicate another view to add rulers to or click the OC button to finish.

4.17 Introduction to Subpictures

When a view is created it will display model objects which will consist of components.

Each view and its component parts will belong to what is called a subpicture.

Subpictures consist of up to 3 levels:

 View – The complete view as created by Symbolic View or Model Views.

 Subview – This is the individual object, i.e PIPE, EQUI, HPANEL etc. Obviously there may be numerous subviews owned by a view.

 Component – This is the individual part of the object, i.e. flange, valve, stiffener, plate etc.

To manipulate the subpictures in the drawing the levels are numbered as indicated below:-

 View – Level 1

 Subview – Level 2

 Component – Level3

4.18 The Drawing Structure

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.

4.19 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 function Tools > Subpicture > Current… 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).

 New subpicture (manual): Create a new subpicture, the user defines the level by indicating the owner. If the owner is at level 2 then a level 3 subpicture created and so on.

 New View: Will create a new level 1 view with a user-defined drawing scale.

 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, i.e. text, geometry etc.

Level 1 Level 2 Level 3

Drawing View

Sub-View Component

OMPONENT

4.19.1 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 application pull-down menu or select the Current Subpicture button on the Subpicture toolbar. The Current Subpicture menu is displayed:

Select Existing component then indicate an existing subpicture. CP (cursor position)

View the Message Window to check the status



Care must be taken when considering the hierarchy of the subpicture structure. Adding text and geometry to a component will result in these elements being removed if the owning sub-view object is exchanged, deleted or updated.

4.20 Create New View (Level 1)

To create a new subpicture, select one of the New options from the form

To create a new view (Level 1) with the default scale, click the 2 New subpicture (manual)

Click Operation Complete to make a new view.

To create a new view with a new scale use, New View Key in the desired drawing scale e.g. 100

4.21 Create New Subview (Level 2)

To create a new subview (Level 2) select, 2 New subpicture (manual)



There must be an existing subpicture.

Indicate an existing subpicture (Level1) and choose Level 1 View the Message Window to check the status.

4.22 Create New Component (Level 3)

To create a new component (Level 3) is with option 2 New subpicture (manual)



There must be an existing subpicture.

Indicate an existing subview (Level2) and choose Level 2

View the Message Window to check the status.

4.23 Transforming a Subpicture

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 section entitled Re-use of Subpictures.

To transform a Subpicture select Modify > Transform>Subpicture… from the application pull-down or click the Transform Subpicture button on the Subpicture toolbar

Select the subpicture to be transformed.

Choose a level using the Subpicture Level tool bar.

1. View.

2. Subview.

3. Component.

The subpicture is highlighted. It can now simply be dragged to a new position or rotated after clicking (Options).



All of the transformation options are available.

After the subpicture is moved to the desired location click (Operation Complete).



In reality the above is a bad example of a transformation because this will be undone if the Hull Panel is exchanged or updated. Also the drawing does not give an accurate reflection of the modelled elements.

4.23.1 Ways to Transform.

When an entity is selected for transformation, the Transform toolbar will be displayed.



When transforming it is important to look at the Message Window to see what the system is expecting. It must say 'Choose

transformation' before the Transform toolbar options can be used.

The most commonly used transformations when laying out views in a drawing are Scale, 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. However all options on the Transform toolbar have been shown here some of which are more applicable for geometry.

Scale: Key in the absolute scale of the subpicture i.e. key in 25 (scale 1:25) Click the OK button, OC.

Move Delta: Key in an offset value to move the subpicture, i.e. 100 U, 100 N

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

1. Select a reference point relative to the element,

2. Then a new point where the reference point is to move.

Rotate Delta: Key in an angle for the element to rotate by. (It will rotate around a predefined centre, +ve = anticlockwise).

Rotate two positions: Rotate by two reference lines both fixed at the centre of rotation.

Rotate predefined angle: Rotate by 45, 90, 180 and -90 degrees respectively.

Mirror: Mirror around the horizontal or vertical axes or parallel to a line.

1. NODE

POINT 2. MID

POINT

Parallel: Transform an entity so an edge is parallel and a distance from another straight line.

1. Select a segment on the item to transform 2. Select a segment to be parallel to

3. Key in the distance from this segment.

Four positions:

1. Transform by defining an axis between two positions 2. Then a new position for this axis (two more positions)

Same as: Transform the same as existing Subpicture; scale rotation and mirroring are accounted for

Along curve: Will transform an entity such that it will follow the path of a curve.

1. Indicate curve

2. Indicate where on the curve the entity is to be placed ( for start).

RESULT

2. Nearest

1a. Node 1b. Midpoint

2a.

Intersection

2b. Nearest

3. Indicate part of the entity to be tangential with the curve i.e. on the curve.

4. Indicate what part of this line is to be on the curve ( for start).

5. Click to complete.

Lock V: If this is clicked before making a transformation the vertical component will be locked and only the rotation or horizontal position can be changed.

Lock U: If this is clicked before making a transformation the horizontal component will be locked and only the rotation or vertical position can be changed.

Change centre of rotation (symmetry): By default a centre of rotation at the centre of the

circumscribing rectangle is used for rotating transformations. This function can be used to move the centre of rotation and the point of symmetry for mirror functions.
