Mesh

From NURBS Object

The Mesh command creates a polygon mesh from a NURBS surface or polysurface.

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.

Note

The meshes created by the Mesh command are editable, and separate from the objects they were created from.
The meshes created by shaded viewport display modes are not editable. They can be updated from the objects with the RefreshShade command, and can be extracted with the ExtractRenderMesh command.

Seamless (watertight or closed) mesh

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.

Steps

Select surfaces or polysurfaces.
Preview the mesh and set mesh options.

The slider roughly controls the density and number of mesh polygons created from NURBS surfaces.

Mesh wires are drawn in viewports for preview, and the dialog box stays on screen for more adjustments.
