When FACETRES is set to 1, there is a one-to-one correlation between the
viewing resolution of circles and arcs and the tessellation, a means of
subdividing the faces of solid objects. For example, when FACETRES is set to
2, the tessellation will be twice the tessellation set by VIEWRES. The default
value of FACETRES is 0.5. The range of possible values is 0.01 to 10.
When you raise and lower the value of VIEWRES, objects controlled by both
VIEWRES and FACETRES are affected. When you raise and lower the value of
FACETRES, only solid objects are affected.
In the following example, smoother geometry is displayed when FACETRES
is set to higher values. FACETRES = 5.
