Create Library Feature Data Object and Library Feature With References (VB.NET)

This example shows how to create a library feature with references in order to position the library feature on a model. First you create the library feature; then you access it to set references.

' Preconditions:
' 1. Model and library part exist.
' 2. Model is open.
' 3. Plane1 and Point1@Location Point sketch point features exist.
' Postconditions:
' 1. Library feature defined and initialized.
' 2. Library feature created on selected face on the model.
' 3. References set for library feature to position
'    it on the model.
