Hello,

Yes, the PDF is the tutorial I was referring to, did you also happen to see the model file you could download that went along with the PDF?

If it is your intent to eventually have your models produced there is an advantage in putting your time and effort into NURBS than polys. I've found that staying in NURBS can act as a check on your design to keep it in the realm of manufacturing. Your clients may also be able to appreciate this as well, since you aren't giving them something that is nearly impossible to prototype and/or manufacture. Having a good understanding of continuity as it relates to automotive design is probably worth your time to learn about. The AD Shape Modeling plugin (originally VSR) was written by some guys that worked on ICEM Surf. The plugin allows you to accomplish more advanced surfacing (e.g. see the models created by Rauol), while being confident that your designs can be prototyped without so much rework.
