I'm familiar with the long way around. Rhino itself doesn't have texture tools per se - textures are added through whatever renderer is plugged in. What it can do is convert nurbs surfaces to meshes with control so that the meshes and the corresponding UV's can be used elsewhere. .step files are small and accurate, that's the attractive thing about using Carrara as a renderer for solid modellers, especially for cad programs using Lightworks as a rendering engine [which is most of them]. I've seen some nice Lightworks renders, but its not very flexible and the implementation in TurboCAD is clunky. The Carrara renderer is generations ahead on all counts [in my opinion]. Currently I do the solid modelling in TurboCAD and export/import .step files into Carrara. Anything that's too curvy for solids I do in Rhino. Both Rhino and TurboCAD imort/export .step quite well and I guess the work around is to export files from Rhino that need detailed texturing as .obj files [instead of .step] and put everything back together in Carrara. I'll keep playing with it - there's lots of longer ways around, you just have to look for them :)
