I have recently began to use inventor v10 alot and i am really starting to get a good grip on most of the functions. For some reason i can not understand workplanes at all. Everytime i create one its usually a guess and normally i dont get the intended results. So basically i guess what im asking is, is it really that hard to create a workplane exactly how i need it and if not can someone please clue me in on how to control it. Thank you.
