Get Sketch Regions Example (VBA)

This example shows how to get the sketch regions in a sketch.

'----------------------------------------------------------------------------
' Preconditions:
' 1. Open a model document that contains a Sketch1 feature with
'    one or more sketch regions.
' 2. Open the Immediate window.
'
' Postconditions:
' 1. Gets each sketch region.
' 2. Press F5 at each Stop statement.
' 3. Examine the Immediate window.
