BimDrag is a very powerful command. If you drag a face of a solid, other solids that adjoin it will automatically change as well. In many cases you want this behaviour.
To avoid this behaviour however, you have to make the other solids invisible or freeze or switch off their layers, which is not always desirable. Locking layers does not work.
Is there a way to lock adjoining *visible* solids to stop them from changing?
Using 3D constraints (rigid set) seems 'over the top' for this purpose.
The opposite can also be required:
In a crowded 3D model you may have to make adjoining geometry invisible to get to the face you want to drag, and yet want the invisible solids to update.
