Replace Sketch Relation Example (VBA)

This example shows how to reassign a sketch relation from one sketch line to another.

 

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

'

' Preconditions: SolidWorks is running and contains

'                Sketch1 and Line4@Sketch1. Sketch1 contains

'                a sketch line that has a horizontal constraint.

'               

'

' Postconditions:  The horizontal constraint is reassigned to

'                Line4@Sketch1. The example also changes the suppression states

'                of all of the relations in the sketch.
