I'm trying to build a victorian, metal chair for a game art project. As the back is these spiraling wires I thought it would be best to draw the curves with curves, extrude a triangle along them, and then simplify and convert. Did I meantion that I rarely ever deal with NURBs?

Have I been an idiot to think I could use NURBs this way? I could just go over and poly model it, but I'd like to know if this is even possible for future endevors.

And the problem would be.....


If it's for a game, and the chair isn't an important aspect (or is it...), why not use a transparency mapped image on a plane?

Well the problem is that that I can't get the model to simplify the way I want. Instead of having a single plane per side on the three sided wire, it's always giving me a mess of them. I just rarely use NURBs and don't know how to make this work though it looks like it should.

Also, I said I can do it with alternate means (several), but I don't like to hit a wall and avoid a techique just because of my own inexperiance with a tool. As this is a personal project and there's tons left in the scene to model, I'd like to know how to do it with NURBs for future referance, even if I don't use it on this chair in the end.

No matter what settings I use to things, it's always an ugly mess when I convert it to polys. I know I could do it with a Max loft, but as I'm using Maya, I just have NURBs. Am I trying to make NURBs do something it can't? Any tips would be appriciated.

Hi askaniblue,


what are your extrude settings:

Style: Flat
Result Position: at Path
Pivot : closest end


try 'General' for tesselation method

set to 3 per span (NOT SURF) for U avd V


Cheers

This might help if you want to go back into polys---

Get the definition you need using the nurbs geo. as a final step convert to polys (I think its in the edit menu)

I like to use

1 per span in both U and V

but use that to you personal disgresion
