Hi, is it possible to create solid geometry from polysurface in Z vector direction in Dynamo? I can see I can create only thickness. I have polysurface from TIN Surface from Civil 3D and want to create few layers as 3D solid in area constrained by polyline as output from Dynamo geometry.

This works for me:
