Difference between Blender NURB and Rhino NURB?

Support Basics & Interface
1

Emm, how do Blender NURB measure up with Rhino NURB? Any opinions?

2

What is the purpose of your question? I am a Rhino user and I have been successful at creating models in Rhino and importing into Blender via VRML. As far as I know there is no way to open Rhino NURBs directly in Blender.

Hi ACK Design!

You sayd it´s not possibel to open Rhino Nurbs directly in Blender. Is there Any chance to open them indirectly via Iges,Step, Wavefront OBJ ??

Is there any way to get nurbs data into Blender?

Rhino3D has a wide variety of export options - the most I’ve ever seen. I will create a model in Rhino and export it as VRML1. These open quite reliably in Blender. There is no way as far as I know to import NURBS directly into Blender. Unless of course someone want to write an import script for Rhino models. (anyone… :-? ?)

A NURBS surface is a NURBS surface (4 sides, parametrization…) in all applications that support it. Rhino, as well as Maya has many tools and options for building and refining curves and NURBS surfaces. Blender lacks the advanced NURBS tools (fillet blends, deformable NURBS…), but it has the basic surfaces to be tweaked by moving points.

The sad thing is, before you export a NURBS suface…you must convert it to mesh. The results are not always pleasing.
A better option is to export a control polygon of your object. Just select the object…and in the command section (at the top of the Rhino ui)
type ExtractControlPolygon . This can be exported in a variety of formats suitable for Blender. Remember to simplify or reduce the mesh to eliminate unwanted triangles. Once the model is in Blender, simply subsurf it…there you go.
