Why do you need to automatic select between drawing an object and making a
hole for it? To me they are completely separate operations and I am quite

the object to the panel to make an assembly. If the panel is part of a 3D
printed object then the hole subtraction is done in 3D but if it is a
milled sheet then the the subtraction is done in 2D and extruded for the
