I tried out the new features in FC 0.18: https://www.freecadweb.org/wiki/Release ... _Workbench
and therefore checked the option Preferences → Sketcher → General → Hide base length units for supported unit systems
result: the unit "mm" disappears correctly from linear measures but not from radius measures:
It seems that this is a bug, right?
