Command Name


This command helps user model NURBS surfaces from selected mesh, e.g .obj mesh. The NURBS patches reach exact G1 continuity on transition boundary.

Command description:

To model NURBS surfaces from selected mesh:

1. Click Faces from polygon from the RhinoResurf menu or type RsFaceFromPolygon at the Rhino command prompt.

2. Click left-mouse button to select the mesh which will be used for surface generation, then click right-mouse button.

3. Wait for a while, NURBS surfaces will generate.


* This command create NURBS surface which are similar to the shape of the selected mesh, but the surface do not fit the mesh in high precise;

* The mesh element number should not be very large. Generally, stl mesh is not suitable to use this command, but obj mesh is suitable for this command.

* If your mesh has too many triangles, it is better merge the triangle to be quad firstly.

The following three pictures show a mesh and the NURBS surfaces modeled from the mesh.
