Hi Kim! Thanks for your reply! this is wonderful. I know rhino would be easier but I’m trying to learn basic modeling in grasshopper.
This is great though. Thank you!

Controlling twist more efficiently

Two controls in the dark blue group allow twist to start on any side and be clockwise or counter-clockwise: [controlling twist_2022Oct25cc] controlling twist_2022Oct25cc.gh (46.4 KB) The red groups are pieces of the final structure, a ‘Closed Brep’ (“solid”).

Selecting specific faces from list of breps

You have modified the code in unfortunate ways that make it harder… From last October: [image] P.S. I added the gray group (below) to the old code. It isolates the surface fragments above and/or below the twisted (non-planar) surface. [controlling twist_2023Jan12a] controlling twist_2023Jan12a.gh (37.0 KB)
