for a start down load the free tuts, the names of them will help you get what you need quickly, they are about 10 minutes each and you will be a million miles ahead and will understand the answers that are given to you, maya is a language as much as an app.

cheers and good luck, if you get no joy, I'll help you or one of us will but get those tuts into you.

some of the answer goes like this.., 'depends if you use nurbs or polygons'.., with me there??
