I want the cross section of my corrugated sheet along the blue line. How do i do that, whether to use grasshopper or rhino? i have tried loft, sweep1, sweep2 etc. nthg worked for me.
Upload a file or something - not sure how anyone can help with just a picture. What’s stopping you from creating the shape you want?
use the command Fin, use the surface it lays on as the base then use Intersect with the resulting surface and your structure.
