Where do you get the idea that an 'International Building Code' exists?

I think that I already have a fix for this. See https://forum.freecadweb.org/viewtopic. ... 27#p581127
It is one of the PRs that I have 'parked' during the feature freeze.

The Ctrl+Drop behavior has changed between V0.19.1 and V0.19.2. In V0.19.1 you can hold down Ctrl and Drop an object nested in a Group on a Layer, the object is then added to the Layer and not removed from the Group. In V0.19.2 and later this is no longer possible, the object is first removed from t...

What is your reason for putting the Subtraction object in a different Std_Part, with a different Placement, from the component that you want to subtract from? Can you clarify your intended workflow?

Holding down the Ctrl key should govern this behavior IMO.

... Actually the Layer class already has a addObject method. But this never executes AFAICT.
