hi,
i’m just getting into Maya 4.5 (PLE) and there are 3 things that are bugging me and i can’t find specific answers to them anywhere…
-
lets say i have a poly cube, and delete one of the faces. If i then realise i needed that face, how can i get it back (apart from recreating it, because if it was a more complex thing i’d been working on I wouldn’t want to have to redo it all).
-
with a sub-div object, can i delete/undo a whole level of detail? i.e I made a shape, then needed some precision so went to ‘refine’ but then end up not needing it… how can i restore it to a simpler form?
-
how do i add points to a curve i’ve drawn? Not adding more to the end, but in effect dividing the path i’ve already got into more segments.
thanks 
sorry they’re such n00b Q’s, but i can’t find the answers in tutes or anything, and my help files won’t work for some reason.
Stuart
