Hi I'm learning maya in college right now and i'm having a problem with a project at the moment. I basically must use curves ( or nurbs I don't even know anymore ) to buid this completely. I have to build this thing: http://www.jeremielaflamme.com/cours...ign/index.html and i'm at the part of Birail 2 , this here: http://www.jeremielaflamme.com/cours...n/Birail2.html Also, i'm sorry the tutorial are in french but following the images should be enough to understand my problem I think. So far, I can do the Birail 2 on 1/4 of my cylinder form however I can't Birail 2 on the second 1/4. http://imgur.com/L7yB7Og http://imgur.com/xgR90UL http://imgur.com/iCA3fTQ It's basically birailing on the other 3 quarters but not the quarter that I want. http://imgur.com/p5XtKbW Please help!!! I've been learning to use polygons and I actually got very comfortable with it but suddently my teachers told us to forget everything about polygons and learn nurbs instead. I'm about to pull my hair out. Last edited by TeterPran; 20-10-2015 at 03:59 AM.
