I still not really clear on how to fix it properly, however it seems rotating the additional spheres did the trick (06:57 in screencast). After asking around in forum, apparently it happened because of "coplanar faces issue". It either become distorted, turns completely black, or only half of the dome that generated. I've tried to Google it, but I still can't wrap my head around it.Ĭompared to previous challenges, I think this one is harder than the others.įirst: when the first time I'm working on this, for some reasons when I'm creating the dome part, the model always failed to generate correctly. Could you ELI5 me what's the meaning of normal and tangential faces ? According to wiki, draft only works on normal faces, and can't be used on tangential faces. When drafting the pocket (11:46 in screencast), FreeCAD cant draft the curved face. Learned to use Mesh workbench to generate smooth STL files, so the render are smoother than using the default export menu.Apparently mirror in PartDesign doesn't work for solid, so we need to use Part for that.In this model, I need to use two workbenches: Part Design for making the initial shape then Part workbench to mirror and merge it. Apparently, to fillet all connected edges, we could do it by only selecting one of them.Learned to use a "master sketch", so changing parameter from 1st phase to 2nd phase is quite simple.Fortunately the differences are not too much. Unfortunately, thanks to how FreeCAD handles fillets, in the 2nd phase I have to make a little modification (14:20 in screencast) to the blueprint. I found it when all hole sketches that I made are moving around when I made some change in 2nd phase of the challenge.
There is known issue about topological naming problem.Because of the first point, FC often crashes when filleting, so make sure to save and pray before doing it.There is known issue where fillet might not work (which apparently happened because of OpenSCAD rather than FreeCAD).Only have problems when filleting the edges, which is why I didn't do the 2nd phase. The first challenge, quite straightforward and easy to do. Code: Select all OS: Manjaro Linux (XFCE/xfce)
