Get Sketch Contours Example (VB.NET)

This example shows how to get the sketch contours in a model document.

'----------------------------------------------------------------------------
' Preconditions:
' 1. Open a part that contains a Sketch1 feature.
' 2. Open the Immediate window.
'
' Postconditions:
' 1. Gets the number of sketch contours in Sketch1 and whether
'    they are open or closed.
' 2. Gets the number of sketch segments in Sketch1 and their type.
' 3. Gets the number of edges Sketch1.
' 4. Examine the Immediate window.
