hi to all,

I'm doing all my modelling work of wristwatches in rhino. Now my problem is: how to export these sometimes very complex models to blender. I can use only dxf or vrml. both formats are giving bad results. what could u advise me? when I import the models some surfaces are showing artifacts and so on. I tried to recalculte normals, remove doubles imported in various file sizes...all with poor results....
someone has a solution????

thanks to all,

lukas

Hmm. Have you converted the NURBS to meshes before exporting? If not: do so, maybe the artifects are caused by poor meshmaking, and you might want to tweak that kind of stuff in rhino.

Second you might want to look into using lightwave as intermediate format, maybe they are better. Too bad there is no Rhino NURBS importer yet, but it is coming thanks to Google :-)
The Summer of Code NURBS project (http://wiki.blender.org/bin/view.pl/Blenderdev/NurbsCurvesNurbana) has as goal to complete a Rhino importer as well...

basically your idea seems to be right way of doing it,

but until now the amount of poligons has to be rather huge...
noone knows some good intermediate options in rhino? for me tha varius vrml (better?) or dxf options arent so easy to understand..

I think the best idea is to tinker with the NURBS to mesh tool until you have found the setting that delivers a relatively low-poly mesh, while retaining a good shape. Once your mesh is correct it shouldn't make that much of a difference which intermediate you use.

export in .lwo format....after meshing in rhino. the problem is still the filesize. a watch case with lugs easily reaches 8 - 12mb. this slows down blender and the import time is too long. smaller filesizes produces little errors in the meshes...
its a pity, the render results of blender are too cool...
