After creating a hole in the floor inside the Edit Floor Slab mode how to remove a hole when Recover all button no longer reverts it?
The reason I need to do this is that on the floors with holes in the floor slab Electrical plumbing no longer works. E.g.:
1.create a 2 floor building,
2.make a hole in the middle ground using the Edit Floor Slab mode (remove the whole floor slab)
3.go to Plumbing and Electrical mode
4.create a light switch on a wall
5.put a lamp on the ceiling
6.try to add a Lighting circuit and add the lamp and switch to it - does not work
7. doing it on another floor without a hole in the ground and moving elements to the problematic floor
6.try to draw high voltage pipe from the switch to the lamp either in 3D or 2D - the pipe will flow through the switch and through the light instead of just connecting them as endpoints.
