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
the maximum angle value. This setting is useful if you want to refine the
appearance of small details such as holes or fillets.
Maximum Aspect Ratio for New Faces
Sets the maximum aspect ratio (height/width) of new mesh faces.
(FACETERGRIDRATIO system variable)
Use this value to prevent long, slivered faces. You can specify the following
values:
■ 0 (zero). Ignores the aspect ratio limitation.
■ 1. Specifies that the height and width must be the same.
■ Greater than 1. Sets the maximum ratio by which the height can exceed
the width.
