It works fine with circlular rails, but you can see that for rectangular rails, I get a crazy result.
This is the code:
rectangle sweep problem.py (855 Bytes)
What am I doing wrong?
Update:
It seems broken in Grasshopper, too. You can see it is sweeping the circle but not the rectangle.
sweep1 problem.gh (14.8 KB)
Update2:
Even weirder…it works in GH if I swap the rail and cross-section shape. It’s not giving exactly the result I was expecting, but it is performing the sweep.
Update3:
So, if I swap the rail and shape in the Rhino.Geometry.Brep.CreateFromSweep, it starts working (although I was expecting the sweep to flare outward at the bottom all the way around…which is what happens if you manually perform a sweep1 using the Rhino tools.)
Update4:
Okay, I just realize that when I swap the rail and cross-section, the sweep is skewed because it it is in fact treating the cross-section shape as the rail. So ignore Update3. I still wonder why it won’t sweep the rectangle in Grasshopper, though.
