Summary
The defaults that you set in the Mesh Tessellation Options dialog box control
the appearance of objects that you convert to 3D mesh objects. For a complete
list of objects that can be converted to mesh, see the MESHSMOOTH command.
This dialog box is also available from the Options dialog box.
List of Options
The following options are displayed.
Select Objects to Tessellate
Temporarily closes the dialog box so that you can select an object to convert
to a mesh object. You can select 3D solids, 3D surfaces, 3D faces, polygon or
polyface meshes, regions, and closed polylines.
Mesh Type and Tolerance
Specifies the default properties of objects that are converted to 3D mesh objects.
Settings that increase the number of mesh faces can slow program performance.
Mesh Type
Specifies the type of mesh to be used in the conversion. (FACETERMESHTYPE
system variable)
■ Smooth Mesh Optimized. Sets the shape of the mesh faces to adapt to the
shape of the mesh object.
■ Mostly Quads. Sets the shape of the mesh faces to be mostly quadrilateral.
■ Triangles. Sets the shape of the mesh faces to be mostly triangular.
Mesh Distance from Original Faces
Sets the maximum deviation of the mesh faces from the surface or shape of
the original object. Smaller values result in less deviation, but create more
faces and might affect program performance. (FACETERDEVSURFACE system
variable)
Maximum Angle Between New Faces
Sets the maximum angle of the surface normal of two adjacent faces.
(FACETERDEVNORMAL system variable)
Increasing this value increases the density of the mesh in areas of high
curvature, and decreases the density in flatter areas. If the value of Mesh
Distance from Original Faces (FACETERDEVSURFACE) is high, you can increase
