I made an “elevator island” and I need to mirror it to the south side of the floor from the north side. But when I try to group all the components together I wind up getting the entire floor too, and outer walls I don’t want either. Is there a way to isolate the standing components without getting the floor too? Or do I have to create walls without extruding them from the floor (I only did this in some cases; most come out from other walls).
My model is now 4MB, so I can’t upload it to show you
