Creating Views Using Folding Lines

This task will show you how to add geometry in views using folding lines as an assistant. This is true for any kind of view, as long as the planes they correspond to are not parallel. For example, you cannot have folding lines between a front view and a rear view.
Open the IntDrafting_Views_FoldingLines.CATDrawing document.

Go to Tools > Options > Mechanical Design > Drafting, click on the General tab and deactivate the Grid display option from the dialog box.

Make sure the view in which you are going to create geometry using folding lines is active. 

  1. Right-click the view to used as reference.
    In this particular case, right-click the bottom view (which is not active and therefore squared in blue).

  2. Select Bottom View Object > Show Folding Lines.
     

In the case of more complex geometry, you can select one or more element(s) in the reference view and display the corresponding folding lines. As a result, the views are not overloaded with folding lines.
This is also true in the case of 2D components.

The folding lines appear.

At any time, you can right-click the view and delete these folding line using the Hide Folding Lines option from the contextual menu. 

  1. Click the Profile icon and create geometry in the top view using the folding lines.

  1. Right-click the left view in which you are now going to create geometry and select Activate View.
     

The folding lines disappear.

  1. Right-click each non-active view one after the other and select Show Folding Lines for each view.

The folding lines now appear as shown here:
 

  1. Click the Profile icon and create geometry in the left view using the folding lines.

  1. Click a view and move it.

    You can note that even when views are not aligned, folding lines remain associative.
  • All the above described functionalities are also true in the case of views with a different scale.
  • In a Generative Drafting context, folding lines are not fully supported in the case of aligned section views.
