thanks for the scripts, works really good, but i changed the increments to 1deg.

to answer your question: i'm thinking of things like an etruded pentagon drawn from the top, now you want to go to front view to project a sphere onto the face ,now you want to project a shape onto each of the other 4 side faces. if you could just rotate the front view left or right to align it to the other faces it would be easy to project to them; now i know there are ways to do this but i don't think they are simpler.

actually a view/align to selection would do just as well, maybe better!

something occured to me as i typed this out; it seems to be more complicated as i think about it because it seems right now that there are only 2 planes in MOI so i guess this would also involve having surface planes too or it would'nt be as useful as i imagine ;-(
