Introduction to Maya - Modeling Fundamentals Vol 1
This course will look at the fundamentals of modeling in Maya with an emphasis on creating good topology. We'll look at what makes a good model in Maya and why objects are modeled in the way they are.

Adding thickness to a trimmed nurbs surface?

Hi folks,

working like mad to get a lot of things finished off so I've got another question.

AS the image shows, I've projected a series of curves onto a surface, and trimmed to create the cut out I want.

What I'm wondering now is how I can add thickness to the edges of the curves - as if I was extruding if I was using polys. So it's not wafer thin but has a lip where the trim is.

cheers

Hi,

I've tried extruding 2 sets of thecurves, and intersecting the result with the cylinder, trimming what I don't need, and using the round tool - but it doesn't work (fails to compute the result)

Heres what you would have to do. Create another NURBS cylinder inside the first one, but slightly smaller, to create the interior wall. Now project your curves on both of these cylinders. Select the resulting curves on surface and offset a couple NURBS curves from them with a distance of 0. Now loft between the two NURBS curves you made. Then just trim out the design part from the inner and outer cylinders.

Nice one onyx!

Worked perfectly (though I never offset the surface curves - I just extruded straight between the surface curves on each face).

many thanks

Gubar, could you post how it looks now? I am having trouble visualizing this.

Sure,

Here is a very quick render,

as you can see it has thickness now rather than being wafer thin.

Hope that helps,

The effect you are looking for can also be faked by using a material, this then cuts down on the geometry. The simple way is to create a bump map or displacement map of even proportions and appply it with the texture and adjust the bump depth and you can get a more dynamic option as it can be changed more easily.
