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

This example shows how to create a library feature with references in order to position the library feature on a model.

'------------------------------------------------------
' Preconditions:
' 1. Verify that the specified part template and library feature
'    exist.
' 2. Open the Immediate window.
'
' Postconditions:
' 1. Creates a new part containing a boss extrude.
' 2. Creates a library feature data object.
'    a. Initializes the newly created library feature using
'       the specified library feature.
'    b. Gets the type of references required for the library
'       feature.
'    c. Sets the name of the active library feature configuration.
'    d. Selects the face where to create the library feature.
'    e. Creates the library feature.
'    f. Accesses the library feature and selects the edges where to
'       position the it.
'    g. Sets the references for positioning the library feature.
'    h. Updates the definition of the library feature.
'    i. Unsuppresses the library feature.
' 3. Examine the Immediate window, FeatureManager design tree, and
'    graphics area.
