Maya for 3D Printing - Rapid Prototyping
In this course we're going to look at something a little different, creating technically accurate 3D printed parts.

First attempt at a head (alien), having face/surface/extrude face problems

Hey, it's me again user added image

I'm having problems getting this right. I'm trying to make a mouth, but when I work on one side and section of faces, the opposite side is distorted, pulled in, etc. What am I doing wrong? I'm just selecting faces, extruding, etc. trying to make a mouth.

My best guess is that your model has Vertex Backface Culling turned on so that when you pull verts on one side, the other side isn't going evenly. Try turning that off and see if it helps.

Go to: Display--> Custom Polygon Display (click on that little box to the right)

At the bottom you have Backface Culling pull down. Make sure Backface Culling is ON. This will allow you to select only components that are facing the camera. Anything "behind" what you see in the camera will be ignored.

To turn it off...go back to the pull down and pick OFF
