Create a Thread Feature Example (VB.NET)

This example shows how to create and edit a thread feature.

'----------------------------------------------------------------------------
' Preconditions:
' 1. Open:
'    public_documents\samples\tutorial\api\holecube.sldprt
' 2. Open an Immediate window.
'
' Postconditions:
' 1. Creates Thread1.
' 2. Modifies the start angle and overrides the pitch of Thread1.
' 3. Inspect the Immediate window.
'
' NOTE: Because the model is used elsewhere, do not save changes.
