Facets are the underlying components of each mesh face. You can increase
the smoothness level up to the value of
SMOOTHMESHMAXLEV (page 1481)
as long as the number of faces does not exceed the value in the
SMOOTHMESHMAXFACE (page 1480) system variable. If you select multiple
objects with differing levels of smoothness, their respective levels are increased
by one.
You can only smooth mesh objects. However, you have the option of
converting some types of objects to mesh during the smoothing operation.
You can also filter out ineligible objects that you do not want to convert. For
a list of objects that can be converted, see
MESHSMOOTH (page 640).

Summary
You can rotate the edge that joins two triangular mesh faces to modify the
shapes of the faces. The edge shared by the selected faces spins to intersect
the apex of each face.
