Thanks for answer!
I select the curves green and white, and then i select the middle and right curves.
I think surface will create follow the middle and the right curves, starting from the green curve

Hello iJIM,

You are on the right track but to get the result I believe you want you would need to do a birail+2 operation and two boundry operations at the front and back of the seat. Then rebuild the three surfaces, convert to polygons and combine them.

I will record a video for you to demonstrate the process, which is probably more complex then just starting with a nurbs sphere and sculpting the seat, but I cannot resist an opportunity to demonstrate Maya's nurbs tools. Although antiquated and in serious need of some developer love they can still be very helpful if you can deal with their many quirks (smile).
