To explain this rather short answer: there were several thickness related posts today where such issues are explained. It boils down to: Yes, there are these issues. And more cannot be said.

Couldn't resist :mrgreen: . You have to model the material you want to take away using other subtractive features.

Will the inside have to be made in the same way as the outside?

Yes :mrgreen:

It is a well known issue. It is from the 3D engine that FreeCAD uses (OpenCascade OCCT).

FreeCAD has little or no influence on the development or improvement of OCCT.

In the mean time most of us have learned how to do such things without the Thickness tool. Like pocketing out the insides.
