View Sets an Overview
When you create a drawing two things happen:
1) On the OneSpace Designer side a View Set is created. The View Set is attached to the model.
- The View Set is made up of view planes. Each View Plane corresponds to a view.
- View Planes are stored with the model and are used to create the 2D geometry.
- View Planes can be toggled on/off using the browser.
- Think of View Planes as the location from which you would look at a model in order to determine what edges should be placed on a drawing (in FRONT, on TOP, on RIGHT).
2) On the Annotation side, a new drawing is created, the drawing contains three items:
· Sheet
· Title block, (frame)
· Views, (FRONT1, RIGHT1, TOP1, etc.)
- 2D Views are stored in the Annotation drawing file.
To retain the associativity between a 3D model and a drawing, both must be saved after any modifications.
BEST PRACTICE: When working on a drawing, load the associated model. This will insure that new views are captured with the model when the model is saved.
Renaming View Sets
BEST
PRACTICE: Rename your view sets.
- Give
the view set a name that describes the drawing
- Using
the drawing number as the name will help you keep track of what drawings
are associated with the model.
- Right
mouse click on VS1 and select Rename.
Deleting View Sets
- When a drawing is deleted the view set remains with the model and should be deleted manually in order to keep confusion to a minimum.
BEST PRACTICE: If a drawing is not going to be used, immediately delete the View Set that was created when the drawing was created.
Drawings
of Assemblies.
- To make a drawing of an assembly the view set must be owned by the assembly.
Everything that
you want to see on a drawing must be contained in the assembly that owns the
View Set.
- Ownership of a View Set is determined when drawings are created.
- Note, Everything in the assembly does not have to be shown on the drawing. Use View -> Manage ->Contents ->Remove/Add parts.
- View sets appear automatically in the structure browser under that part or assembly of the model.
- To make a drawing of a part, select the part to be the owner of the View Set.
A Bit More Information
- Unless deleted, a model that has many drawing attempts will have many view sets.
- When a model is loaded OneSpace Designer scans the model for View Sets.
- All View Sets are then displayed in the View Sets window (under Views in Annotation).
- There is not necessarily a drawing associated with each view set.
- When a drawing is loaded Annotation scans the view set list looking for a match.
- If a match is found then the view set name is displayed in the “Active V-Set” box.
- Additionally, the views in the Drawing Browser are displayed in dark blue.
Checking
Associativity
If the model is not loaded (or is not associated to the loaded drawing), the Drawing Browser shows the views in red.
Blue indicates the loaded drawing and loaded model have view sets that match each other.
Setting
view directions Up / Front
· When creating a new drawing you have the option to set the Up and Front view directions.
· OneSpace Designer selects the active part to determine the default Up and Front directions.
· If the Up/Front arrows are “way out in space” it is because the active part is not being displayed in the view port.
· You can specify your own view directions. After defining the directions the Front view will be displayed on the drawing as it is seen on your screen. The Top view will be shown as if you were looking down at the model from above.
BEST
PRACTICE: Always define your view directions, don’t use the defaults
Procedure
for attaching views to a different model.

Leveraging
your work…
Situation:
- You have a fully annotated drawing of a model, the drawing contains dimensions, and text that describe the fabrication or assembly of the model.
- You now want to use the model as the starting point for a new project.
- After modifying the model you need to create a drawing, however you would like to use your existing annotated drawing but have it reflect the changes you have made to your model. You don’t want to create a new drawing from scratch.
Here is the procedure:
1) Copy the model, this will also copy the view sets.
2) Load the drawing, detach each of the views from the model using Migration Tools.
Detached views are shown in red.
3) Reattach each 2D view to the 3D view of the copied model.
Drawing browser will now indicate that the view is attached (light blue).
After updating Drawing browser will show the view in dark blue.
4) Save the drawing with a new file name, do not overwrite your existing drawing!
The
Dreaded:
Reasons why you get this error:
1) You don’t have the correct model loaded.
2) The model loaded does not have a view set that matches the view set of the drawing.
Top 3 reasons why the model might be missing the correct view set:
1) The model was not saved after the drawing was created.
2) The wrong model is loaded, your confused, start using WM.
3) The model was saved then in the same session undo was used.
What to do…
1) Load the drawing and print it.
2) Write down the names of the views shown in Red from the drawing browser.
3) Delete the drawing.
4) Looking at the paper drawing determine the orientation of the views (Gen1, Right1, Top1, etc.)
5) Looking at the paper drawing determine who owned the view set, is it an assembly or a single part?
6) Load the correct model.
7) Create a drawing the set the owner of the view sets as needed (see step #5) and set the correct Up and Front orientation.
8) Create views on your new drawing the correspond to views on the old drawing, this may be difficult with respect to general and cutaway views.
9) SAVE THE MODEL!
10) Delete the drawing.
11) Load the old drawing.
12) Cross you fingers and update the drawing.

Light blue indicates the associated model is loaded but views have not been updated.
