How to make complex profiles in dynamo?

Hey guys. I just recently learnt Dynamo and wanted to make the surface of a tall building in dynamo. The shape of the building is quite complex and i need different profiles at various levels to finally join them altogether and form the building. But the problem is i don’t have any idea how to create those complex mathematical profiles. I heard we can import profiles from AutoCAD too.
Please briefly help me by telling briefly how can i make those complex profiles. Thank You.

Polycurve.ByPoints should do the trick.
