Hi,

I am a maya newbie trying to model a car using nurbs.

I am stuck on this part. I need to make a smooth surface (area b/w fender and hood) and I using 2 1-birail's. Can someone please tell me how to make a clean smooth surface by attaching the 2 and remove the sharp edge b/w the 2 surfaces while kepping the sharp boundaries intact??

Thanx a ton

Sami

I just knew a bit abbout nurbs but by the way you explain it I cannot see your problem clearly - perhaps it is just a lack of knwoledge or concentration

what for sure cannot be wrong is to go through a guided nurbs car tutorial before you try it all on your own - nurbs are pretty tricky

Without getting into too much detail you can either Stitch the two edges or you can Attach them.

Use Stitch if you want to keep the surfaces separate but you need them to be tangencial. Use attach to turn 2 surfaces into 1 surface.

You don't need to attach your surfaces to get a smooth transition if the curves you used to create them are tangent you can achive the same result.

Even if the curves aren't tangent won't stitch make the surfaces tangent if you select Tangent in the stitch options?

Stitch won't make them tangent as such attach will.

If you want good surfaces you need good curves, also when you create surfaces use existing surfaces as edges as you can because with the sqaure tool you can specify tangency on that edge.

Kabab,

I'm not trying to argue with you and I'm certainly no expert on Maya Nurbs.

The Stitch Edges tool can make the surfaces tangent. I'm not saying you shouldn't draw your source curves correctly in the first place, but if you have 2 surface that are a little off you can and probably should stitch them to get the required tangency.

See attached pic.

Whoops you are correct i missed that tangent button :) But you are better off having good curves.

thanx guys, scott, kabab and everyone else... i think i'll work on improving the curve... btw, don't stitch/align-with-attach-option/attach do the same thing? they sound like they do but i guess there is a diff.. anyplace where they are explained in detail? A|W's online help is really bad... sort of like Stalling's OS book... only the author or an expert knows what it all means....

When you stitch two surfaces they stay 2 separate surfaces that are connected at the edge you stitched.

When you attach you turn two surfaces into 1 surface.
