Control: tags -1 moreinfo Hi Mike,
I can't reproduce the issue, can you elaborate how you get the crash? (I've tried on a Body -> Mesh Workbench -> Meshed -> Create Mesh From Shape while having a Body, and a second try reproduce a feature of the Body, selected. Can you share your model that is causing the crash? -- tobi On Mon, 20 Oct 2025 10:45:04 +0200 Michele Cane <[email protected]> wrote: > Package: freecad > Version: 1.0.2+dfsg-2 > Severity: normal > >
