Get Tangent Edges of Bendlines Example (VBA)

This example shows how to get each bendline's visible tangent edges in a flat-pattern view in a drawing of a sheet metal part.


' Preconditions:

' 1. Open a SOLIDWORKS drawing of a sheet metal part

'    that has a flat-pattern view with

'    bend lines with tangent edges.

' 2. Run the macro and examine the Immediate window

'    and drawing document to verify the results.


' Preconditions: None
