Simplify/optimize bottle definition (especially the threaded neck)

If you search for ‘bolt thread grasshopper’ you’ll find topics like this:

Cannot Seem to Make Threads with Grasshopper's Sweep1

But here’s a version of the demo which is done with a proper metric thread profile (a 36x4 male thread): [image] I have added some notes to the grasshopper file: helical thread demo v2.gh (40.9 KB) But I’d stress that this is just a demo of how sweep2 can work OK in grasshopper for this. It isn’t a tool for generating threads (although it could be a starting point for one). Regards Jeremy
