Create Curve Through Reference Points Example (VBA)

This example shows how to create a curve through reference points.

'----------------------------------------------------------------------------
' Preconditions:
' 1. Verify that the specified model document exists.
' 2. Open an Immediate window.
'
' Postconditions: 
' 1. Opens the part document.
' 2. Selects four reference points.
' 3. Creates Curve1 through the selected points.
' 4. Inspect the FeatureManager design tree, the graphics area, and the
'    Immediate window.
'
' NOTE: Because the model is used elsewhere, do not save changes.
