Polygon Mesh Detailed Options
The mesh is created in three steps based on the detailed criteria: initial quads (estimated to roughly meet the criteria), refinement (subdivision to meet the criteria), and adjustment for trim boundaries.
Surfaces are meshed in a two step process. First a regular quad mesh is created and then that mesh is refined by splitting some quads into 4 smaller quads. The Maximum aspect ratio, Maximum edge length, and Minimum initial grid quads settings control the generation of the initial mesh. The Maximum angle, Maximum edge length, Minimum edge length, and Maximum distance, edge to surface settings determine which initial quads get split up into smaller quadrangles.
Options
Maximum distance, edge to surface
Pack Textures
When polysurfaces are meshed, the packed texture coordinates are created. A packed texture is a partition of the unit square into disjoint sub-rectangles so that one bitmap can be used to apply independent textures to each face of the polysurface.
The Pack Textures option will pack the mesh textures of every mesh and render mesh in the selection set. If more than one object is selected, the packing "spreads" the texture over all the objects.

Simple Controls
The Polygon Mesh Options or STL Mesh Export Options dialog box appropriate for the action appears. These simple controls are an alternate way to control the way the mesh is made.
Notes
The meshes created by the Mesh command are visible and editable, and separate from the NURBS objects they were created from.
The meshes created by the Render and ShadedViewport commands on NURBS surfaces and polysurfaces are invisible, not editable, and cannot be separated from the NURBS object, except to destroy them with the RefreshShade command. Render meshes are controlled by a different set of meshing settings, which are on the Document Properties dialog box Mesh page.
