I'm kind of building this way atm:
Building rooms seperately from one another, blocked in by rectangular caulk hull... then I kind of make a central caulk brush inside, which I cut up into pieces with the clipper, keeping all the pieces (temporarily) as brushes. Then I kind of fly in and remove all the pieces that are supposed to be empty space (the interior of the room, all the small exterior brushes made by clipping).
I'm shooting for a cavern interior, so I didn't want to create, shape, and fit each brush individually; is there any serious unforseen problems with building in this fashion though?
Also, can I clip with a brush? (shortcut or whatever is possible pls)
