I'm following along a tutorial on how to make a guitar, but the tutorial is for wings, and I've been using maya, simply to see the difference in tools and workflow. None the less, I came across the need to create a spiral, and in wings, there's a primitive for a spiral. Now, I know in the maya 6 bonus tools there's a tool that creates a spiral curve, which is great, but when I use that curve to extrude it to give it thickness, the spiral is twisted. What I mean is, the nurbs surface follows the curve as it should, but the cylindrical flow of the surface along the curve is twisting. If anyone has used the wings3d spiral, you'll notice that the vertices, edges, line up properly with no twisting. My question then is, is there a way to line up the nurbs (or poly output) surface instead of it twisting around the curve?

I hope that makes sense.

im afraid that doesnt make much sense... you are trying to extrude a Nurbs cylinder (or poly) along a curve, but you dont want it to twist? Maybe you could rephrase that, im just having trouble grasping what excactly the problem is.

I had a feeling that was the case, so I made a quick picture to illustrate my question.

As you can see in the image (hopefully, not the greatest quality) is that the wings3d spiral has a very uniform spiral, vertices align up along the y axis, and the edges and faces are all positioned the same that if you were to uncoil the spiral, all the edges would be 180 degrees to each other. Where as the spiral in maya, the vertices are tilted slightly to accomodate the spiral, and the edges/faces aren't uniform.

It's not a big deal, I can always use wings to create such a thing, but I was just wondering if there was a way in maya to create a more uniform spiral (among other things) like the wings3d spiral

edit: forgot to include the image :(
