Hi again, community!
Back with my next issue. After successfully replicating a couple of 2D drawings to 3D parts thanks to you wonderful bastards, I am currently trying yet another. Seems simple enough:
However, note the red marked basic dimension. Whenever I try to set it I get an invalid geometry error.
Part file with the sketch so far attached.
Can anyone explain why I'm getting this error and maybe offer some help or guidance?
