![]() introduced in version 0. I can't seem to figure out a better way to make threads with freeCAD or fix this. Add Cosmetic Threads: Add Cosmetic Thread Hole Side View: adds a cosmetic thread to the side view of a hole. If I then use netfabb to repair the model (it needs it, apparently), it treats the threads on the inside of the nut like the threads of the bolt, and fills them inwards instead of joining them with the outer shell - thereby filling the nut's ends. I then took a cylinder, created a second one the same size as the outer helix of the threads, and then cut the larger one with the smaller one so that the helix threads fit perfectly in the big cylinder (and there's a hole for them in there). Basically to make the nut I do the same thing as the threads, but I increase the radius of the threads by some small amount to make sure that the bolt will slide in. However, when I try and slice up the nut, I have some real problems I guess due to the "hole"-ness of the helix curves. Dassault Systmes 3D ContentCentral is a free library of thousands of high quality 3D CAD models from hundreds of suppliers. I checked the layers with pronterface, and it all seems good (neat to see the threads being printed. The bolt works pretty well, and with some repairing (this technique does seem to create holes and stuff. The macro linked before is a huge step forward, and I hope something similar ends up integrated in a stable version. ![]() Keyword being almost, as in you can see it happening some time in the future, but right now, it's just not. I think it works pretty well as a technique, and I can then use cubes and stuff (with some effort) to then cut the threads to length. TechDraw (and many other FreeCAD features) are almost ready for prime time. Attached is a picture - I used parametric helix objects, offset them, and then used "Create a ruled surface between two curves" to flesh out the threads. it's just a test) while I wait for my reprap parts to arrive. Hi Guys, so I've taken to freeCad as I'm getting the hang of it, and wanted to make a bolt and nut (this one is round.
