Shaded geometry visualization sometimes does not follow the actual geometry;?
this usually occurs in models that are large in one direction, but small in another direction.?
Modify the shadingquality(N) command (where N is a number between 1 and 10; 5 is the default).
Raising or decreasing shading quality by 1 roughly doubles or halves the quality.
Note, however, that N does not need to be an integer梔ecimal values are acceptable
*shadingquality(5)
The following command controls how surface edges are plotted. The value can be either 1 or 0.
For default value 1 discretization of edge geometry is synchronized with surface faceting
(see previous command). The value of 0 provides finer edge representation (for default
faceting density - value 5 in previous command).
