![]() There's also no special treatment for the ends. Unfortunately as of now rotate_extrude() which should be closer to creating helical objects has learned partial rotations (not supported in 2015 builds for Windows) but cannot create helical extrusions. The problem here is that like fanning a deck of cards you'll end up with tucked-in faces and serrated outsides - as seen on Thingiverse:Īnd here's another one with a bit of discussion from 2014: If you just want the answers, please scroll down :)Īs an example: without an operator that creates dedicated helical structures people are using linear_extrude() with twist to get something helical: ![]() Let's go over what doesn't work (hopefully gaining some insights), then look at my proposed approach. Since OpenSCAD is am open source work in progress, users do not necessarily work with a version that has the latest features, documentation may not be up to date and forum posts claiming "it cannot be done" are repeatedly being invalidated by software revisions, adding to the confusion. What I'm going to walk you through here is a way to create helical thread forms just like the ones you'd strip when overtightening a bolt: In short, what we don't want is unnecessary structure, gaps, holes and mismatch of resolution of the threads and the rest of the geometry.
