hi users, I figure someone on this list has run across this before. I have been using a modeling/CAM tool - Rhino - to generate a 3D model that I would like to import into Chimera, if possible. Does anyone have a "best way" to go about doing this? Rhino is a NURBS modeler that will export as .dxf or .dwg (AutoCAD), .ai (Adobe Illustrator), .fbx (MotionBuilder), .obj (Wavefront), .igs/.iges (IGES), .sat (ACIS), and .stl (Stereolithography). It also saves in its native format - .3dm - but that is a NURBS (openNURBS) format and I realize that Chimera does not render NURBS. Of the export options above, having limited familiarity with Illustrator, I am unsure what the nature of "3D" is in that format. thanks for any suggestions, -Jeff
