wrong work automatic workspiece dimensions

[tcurdt]

The tool path bounds have z height of 28mm. On Automatic with a margin of 5% it somehow picks a workpiece height of 2mm 🤔

Camotics treats all workpieces as starting at z=0 and going negative in z.

The simulation works fine for positive z, but the workpiece representation and the cut representation will not go above z=0.
