DirectShape.CreateGeometryInstance

Description:
Creates a copy of a definition shape that was created earlier.

Remarks:
Use DirectShapeLibrary class to store definitions prior to using them here. How the definitions are stored will determine whether an instance or a copy of the shape will be created. Use the output of this function as input to CreateElement to make the created shape persistent. This is intended to support a definition/instance pattern common in CAD formats - DWG blocks, STEP MAPPED_ITEM, IFC IfcMappedItem.
