If you are in doubt about whether a given area is flat, try to make a planar
surface. A planar surface requires a single closed wire as its boundary.
If the wire is not a closed single loop, you can see the breaks in the wire when
you select it.
You can join line segments into a closed wire that forms the boundary of a
planar surface. The surface is trimmed to the boundary shape.
NOTE When joining line segments, set tolerances to compensate for imper-
fect wireframe data that would otherwise cause the surface to fail.
Determine if an area is meant to be flat. If it is flat within the tolerance, create
a flat surface and adjust the edges.
Choosing a Surfacing Method
