Get Edge Curve Parameterization Example (VBA)

This example shows how to get curve parameterization data for a selected edge.


'-----------------------------------------------
'
' Preconditions:
'       1. Part or assembly is open.
'       2. If an assembly, it is fully resolved.
'       3. An edge is selected in the SolidWorks graphics area.
'       4. Open an Immediate Window.
'
' Postconditions:
'       Inspect the Immediate Window.
