There'sa problem with part 527.dat

[Bertrand Lequy]

Hi, I suppose the matter comes from hi-res primitives, but when I open this file with LDview, and when I render it with pov-ray this helmet is hollowed, and some conditionnal lines don't match the trianlgles.

Problem disappear when I uncheck the primitives substitution. 

Or is it a LDView problem I should post in Viewer's subforum ?
