From NURBS Object
The Mesh command creates a polygon mesh from a NURBS surface, polysurface, or SubD.
A mesh is a collection of vertices and polygons that define the shape of an polyhedral object. Meshes in Rhino consist of triangles and quadrilaterals.
Rhino creates triangles and quadrilaterals meshes for exporting to various file formats. If a mesh is generated from a solid, the mesh will be seamless/watertight.
Rhino creates triangles and quadrilaterals meshes for export into various file formats. When surfaces are joined together in Rhino, the meshes along the joined edge have coincident vertices. If a mesh is generated from a solid, there will be no holes in the mesh. This is valuable for export to STL rapid prototyping files.
Select surfaces, polysurfaces, or SubD objects.
Preview the mesh and set mesh options.
Polygon Mesh Options
The slider roughly controls the density and number of mesh polygons created from NURBS surfaces and SubD objects.
