Get Guide Curves in Loft Feature Example (VBA)

This example shows how to get the guide curves in a loft feature.

'----------------------------------------
' Preconditions:
' 1. Verify that the specified part document
'    template exists.
' 2. Open the Immediate window.
'
' Postconditions:
' 1. Creates a new part document.
' 2. Creates a loft feature.
' 3. Prints to the Immediate window
'    the feature type and feature name of the loft 
'    feature.
' 4. Accesses the guide curves in the loft feature.
' 5. Prints to the Immediate window whether the
'    loft is a boss feature, the number guide
'    curves in the loft, and the feature types 
'    of the guide curves.
' 6. Releases access to the loft feature.
' 7. Examine the Immediate window.
