I used Dynamo to generate massive geometry for the building.  
I have a form in dynamo then I need creative a Curtainwall system in to mass surface.  
So I need to transfer the generated form to the mass unit to create the curtainwall system in Revit on its surface.

I wanna do that…

> @LifeisMyLove Follow these steps … Open a Conceptual Mass family template in Revit Launch Dynamo, add Import Instance.ByGeometry node to the end of your graph and run. The geometry is imported to the Revit Conceptual Mass environment. Load this family into your project. You should now be able to select faces and create a Curtain System

but I cannot divide the surface
