I miss this possibility within Fusion 360.
I was able to do this with Rhinoceros + T-Spline + Grasshopper. First I created a loose model with the needed topology, then moved the vertices of the control polygon to the coordinates I wanted.
It would be so great to include some API funtions to achive this!
At least, a way to input the topology with an adjacency matrix or similar, and the possibility to assign specific coordinates to the vertices of the control polygon.
Also, a way to link points in the model with these control points.
