I've noticed that for complex FreeCAD projects, sometimes selecting a specific object "type" can be quite tricky. For reference Siemens NX (Unigraphics) has the option to only allow certain objects to be selected, which makes life so much easier.
The general idea is to have an unobtrusive dropdown menu with options to pick between:
- No filter
- Solid bodies
- Facet Bodies
At this stage, my proposal is shameless ripoff from what I am familiar with. Perhaps someone might come up with a better integration to the current FreeCAD UX.
