I have just begun trying to learn maya... and am coming from Rhino and am having quite a bit of difficulty learning Maya nurbs after using Rhino.

I'm trying to trim a surface.

I have made a curve and projected it onto the surface and used trim and the result is below.

I have also tried boolean and get the same result.

I have also tried making the patch more dense with increasing the isoparms.... I am completely at a loss.

If anyone can help I would appreciate it.

I think your problem is with tesselesation. There are 2 things,

1. You need to increase display smoothness, hitting 3 will give you better smoothness.
2. When you need to render, check your tesselation by opening the shapenode, find the tesselation tab, turn on "Display Render Tesselation". Maya will display how it will tesselate your object during render.

3. If you found out that you see gaps when it's render, then you need to increase tesselation by:
a. Increasing curvature tolerance to highest, increasing U division and V division, turn on smooth edge and increase smooth edge ratio
b. Activate advance tesselation, play with the value of primary and secondary tesselation.

But I have to admit, the result won't be as clean as Rhino or Studio.

Best regards,

Thanks for the help... does this mean I should just forget about modeling with nurbs in Maya?

I love Rhino, but there are so few firms that use it I wanted to learn something more mainstream... any suggestions?

Every package has their own strength and weakness.

The most important thing is how to get the best out of each package, and finish the job nicely.

I usually avoid Trims in maya. When you use them, the hardware display always messes up but it usually looks fine when rendered.

Anything in particular you are trying to model?

Thanks for the replies... yeah I'm doing a car right now... the trim is for a headlight.
