Hello Jim,
L3P coplanarity checks have some problems (they depend on the size of polygon,
some explainations here: http://www.philohome.com/isecalc/planarcheck.htm). So
coplanarity criteria has been updated
(http://www.ldraw.org/Article512.html#coplanar) but guidelines were not. So the
tool to use is Planarcheck.
