I'm in the process of creating a new product, and I've come to a brick wall. I need to know if there is a way to convert mesh objects into nurbs.

What are your mesh objects? It may be possible to model them directly in nurbs. If you have to match the mesh model closely then these are some options: Geomagic and RapidForm both have semi-automated tools to convert meshes to nurbs; however, both programs are close to $15,000 dollars. A much more affordable solution uses a nurbs modeling app (such as Rhino, FormZ, Amapi, VectorWorks, to name a few) to make a series of sections through your mesh model and then tracing the sections to create nurbs contours. Then the contours can be lofted (or skinned) to create a nurbs surface. Rhino has a plugin called Smurf that assists in the creation of the contours. Chris

in rhino mesh2nurb a command that does exactly that. :)

I believe Rhino's mesh2nurb translates each facet in the mesh to a nurbs patch, instead of creating a smooth nurbs surface that covers the original mesh. Chris

Maybe topology brush can help to trace your mesh to poly and use it in a sub-D or nurbs application. Check out Silo, later release of Zbrush will be able to to that with a more advanced Zsphere technology.
