you're right Ede, however i can do the same with Cinema 4D because it has a direct link for building complex object and the send it to ArchiCAD as a library part ...
but actually i was looking to one of ArchiCAD rivals (revit) and how you can build such forms and at the same time i got so optimistic using morph tool to create such forms, but to remain the leader in BIM and in the Architectural design industry I urge Graphisoft to build such a tool or integrate such forms into CW tool ...
