Get Sketch Relations Example (VB.NET)
This example shows how to get all of the sketch relations in a sketch.
'------------------------------------------------------------------
' Preconditions:
' 1. Open a part or assembly document.
' 2. Select the sketch whose relations you want to see.
'
' Postconditions: Inspect the Immediate window.
