Tower with changing thickness (mabye rotation)

by Steve Schiller

May 16, 2017

Hello people of this forum,

I'm new here and this is my first attempt to formulate a question in relation to grasshopper. I hope I will not fail!

I want to stack rectangles in Z direction, but want to be able to change them in their size while going up.

In the pictures below the red lines are the ones, which form the size of the rectangles. The green line resultates and the blue is fix.

In the added Rhino and gh file I made a twisted tower, in that I wanted to change the thickness of the tower but failed.

So can anybody help me to combine the ideas of twisting and size changing in height?

Or at least give me a idea, how to change the rectangle size following 2 parametric curves like I did in the rhino picture?

Thank you in advance :)

      I drew three curves in Rhino, internalized in this GH: vertical corner line ('Crv1') and two shape curves, one in X plane, other in Y plane.  How you manipulate those curves, and other "bells and whistles", is up to you...

        Refined curves to be tangent to ground, reduced "floor count", added sheathing on two sides by extruding the basis curves, then intersecting and splitting (trimming) the resulting surfaces (green group):

        Note the interesting curve of the corner edge:
