I'm a long-time Open Source enthusiast, and just recently started learning FreeCAD. Fascinating project I must say! Having modeled a few solid things in the past using the wrong tool for that (cough-cough Blender ) I'm shocked how accessible, easy to approach and powerful FCD is. TechDraw workbench deserves special mention (the Drawing workbench should be just removed, I was disappointed and confused by it for quite a while).
You guys, the core team, everyone who contributes, reviews PRs, fixes CI, maintains the wiki, helps on the forums & IRC, etc — are carrying gravely important mission, that's not to be understated.
I do really mean that; but let me move on to something interesting (I hope).
This model I made has two bodies: body base and pulley teeth. The former has holes in it. Hmmm I shouldn't spend words on it, here's how it looks:
The problem is, for a final tech drawing I need these merged/fused (and refined)
... but whichever approach I try, the small holes on the bottom near the teeth disappear:
I tried all of:
- Part Union
- OpenSCAD Union
- PartDesign Boolean
I was careful to not place the holes touching any edge or wall, there's spacing. The diameters of teeth & base body are explicitly set at 90.5; adding spacing between them does not help:
The model was made in v0.18 (r16158) and maybe there's something funny in the document history — as I was fumbling around a lot and had to make several reattachments, recomputes and error fixes.
I tried loading it in v0.19 (r22846-Linux-Conda_glibc2.12-x86_64.AppImage) but that didn't help anything; the holes still disappear with any of the fusion methods.
The FCstd file somehow doesn't fit the forum upload limit; check here https://drive.google.com/file/d/1gdzxJb ... sp=sharing
Can anybody else confirm the behavior? If so, I should probably report this at the Mantis bug tracker.
More importantly for me... are there workarounds I don't see? Perhaps it's possible to erase a circle in TechDraw? I don't really need the parts fused, if not for trying to obtain neat tidy drawing.
