Tower boundary surface

Hi,

I want to filling between two curves of my tower with boundary surface but I cant. how can I solve this problem.

I attached my gh file and a picture for showing what I want.

Thank you

I "cheated" by creating a 'Boundary' surface and then used 'Move' and 'Rotate'. The derived polygon centers ('PCen') for 'Rotate' and 'Scale' is likely a problem, preventing creation of planar surfaces between the rotated polygons. Better to already know those points than derive them; I didn't need one on each floor for 'Scale' since I'm doing that just once. 'Rotate' is happy using the same single center the original 'Polygon' used: 'WorldXY' (origin: 0,0,0).

Thank you very much Joseph.

My pleasure, towers are fun. This is a better way, allowing 'Scale' on each floor, which allows for the inner polygon to taper as shown:

Joseph,
Yes it is better. Thank you again

Yeah, having that rotated reference plane at each floor can be helpful in many ways.

Same code, minor cosmetic and parameter changes... Cheers.

Parametric towers inspire the imagination and are good practice for learning data trees with features like floor-by-floor 'Scale' and 'Rotate' (each of which can be shaped by a 'Graph Mapper'), and diagonal bracing between floors or an exoskeleton, window details, etc.
