Plib snaps vertices together. Yet another "why do we need this?" feature that is always on by default. I think the snap value has been reduced from 1cm to 1mm in plib cvs. Also there is a fix in plib cvs that partially fixes a problem where perfectly good triangles were being found degenerate. When plib finds degenerate triangle it just puts a 1,0,0 normal on the vertices (hence the white). It is still possible for plib to detect a good triangle as degenerate. > > 2.

Some aircraft do a range select on the panel object so that it doesn't show at all when in external views (e.g. c172p-3d). Maybe that is where the confusion is.
