It is, RAM usage is absolutely wild on it and it needs constant reboots.

Can it export STL/3MF without making all the circles low poly yet?

Last time I tried it freecad was not usable for 3d printing because it doesn’t export properly.

With the naming bug that still exists too I found it basically unusable even for basic parts. It feels like going back 20 years compared to fusion 360.

That is an insane bug to have in your CAD software, I don’t see how it’s usable for any slightly complex part.
