Example 6: Adding Associate Relationships
Obtain <Feature Model> of the building in the model library.
Call SE_AddAssociateRelationship().
Pass NULL for the link object, since there is no link object for a <FMI> => <Feature Model> associate relationship.
Pass SE_FALSE for make_two_way, since this will only be a one-way associate relationship.
