I’m trying to create a parametric window, based on factory drawings of the window. When I sweep the frame in Rhino, it’s perfect, but when I do exactly the same in grasshopper, the section gets wider in the vertices of the sweep rail (a rectangle with the size of the window).
Is there any way to solve it? My alternative solution might be adding diagonal plane to the vertices and trim the excess of individual edges sweeps, but I find it a bit messy.
1st-Sweep with Rhino
2nd-Sweep with Grasshopper
