I made some assemblies in Autodesk Inventor. Within this assemblies i created different variants with iAssembly.

When i export my model to Revit with BIM Support, i can't find this variants in Revit.
I want to make the same variants in Revit so that our costumers can choose them with a yes/no parameter.

Is there a way to achieve this? Is this a option in Revit or is there a other method?

Thanks in advance!
