i've looked all over the place, maybe i'm just not using the right words and i feel like an idiot asking this but...
how do i go about joining brushes so what when i load up may map they are "stuck" together?
e.g. say i made a desk from 5 brushes (4 legs and 1 top) how can i join them so in game i can pick it up and throw it around like one of valves prop models?
