I thought I would knock some dust off my drafting skills after a small chat with @captain_aggravated@sh.itjust.works
Seeing this image on the tutorial made me realize, FreeCAD seems to be a Technical Geometry Super-Suite. It makes sense that CAD would grow to include all of these things. But I thought sharing the initial perspective of some one who hasn't looked at this stuff in about 18 years might be interesting.
Granted I'm not actually familiar with most of this stuff, and none of it from the POV of FreeCAD. If this can deliver 10% of what I'm looking at, I'm in for a treat.
I've used it for making models for 3D printing for about 5 years, never seen that issue
Strange, when I looked it up at the time there were a bunch of suggestions for defaults to change and stuff to try and solve it.
You can print circles and not have them come out with flat faces instead of an actual circle?
So I guess it's only an arc and not a full circle, but I had no problem making this curved sanding block in FreeCAD.
Yes. I just did a few days ago actually. Made some 4 mm diameter washers, they look perfectly round.
Have you tried using the mesh workbench rather than just exporting as STL?
