160 - Grasshopper - Perforations on Warped or Parabolic Surfaces - CircleCNR SDivide SDiff 

thanks for posting. for such simple tasks you can also unroll surface uv, array holes there and either make a perforated surface/solid and re flow it, or reflow curves on surface and trim. Much less computations, less steps, faster interaction and geometrically correct, as the holes will have the natural distortion manufacturing will have (cutting and perforation first, bending last).

SOME TEP IS MISSING IN THE (CUT) AFTER 12 : 40 SECONDS

Interesting video! Lots of possibilities with this software.

Solid is union is not working, its odd because th cylinders are appearing

why not all video

Thanks for the post, I got this warning at the first step however... Subsurface is invalid because the trimming U-domain is singular. Any thoughts?

Wow! Thank you!

What command would you input if you want to increase the amount of vertices ?

What does reparametarize option do ?

Have a problem, circles do not appear in 4:20. why?

what happen ? 12:45

"1 foot" hahaha
