There should exist checking of degenerate triangles
(i.e triangles forming 0 surface area) prior to
importing into a brl-cad geometry database file.

    Almost all the converters have checks for degenerate
    triangles, including the Pro/E, Unigraphics, DXF, STL, and
    Fastgen4 converters. Most eliminate any triangle with a side
    less than 0.005mm long. Some allow this value to be changed
    by a command line option. If you have an example where
    degenerate triangles are not being eliminated, please
    provide it.
