Create 3DContact Feature  (VBA)

This example shows how to create a 3D contact feature for use in Basic Motion and Motion Analysis studies.

'------------------------------------

' Preconditions: Assembly document is open and Motion Study 3 exists.

'                SolidWorks MotionStudy type library is referenced.

'

' Postconditions: a 3DContact feature is created.

'--------------------------------------
