While using slab6 we all know the controls for turning camera angles are whack so I've figured out an easy solution, just get as close to what u are modding as u need to be and press (,) turns right (.) turns left (page up) pans camera around the top to bottom of the mod (page down) pans camera around the bottom to top of the mod hope this helps :)
COMMA:Turns around the mod only
period:turns around the mod only
page up loops around the mod only
page down loops around the mod only
if its not clear enough just go in slab6 and try it urself
