combine and intersect are only valid for multi-body parts.
use the indent feature when editing a part in an assembly to make a cut-out with an offset.
target body - body that recieves the cut (in the part being edited).
tool body region - parts or bodies that do the cutting.
cut - if checked offset will be 0.00
Also why T1 (whatever it means) gets greyed out with a value when I choose the "cut" checkbox?
