The primitive substitution on this mixed-mode primitive is not made correctly. The issue is visible on the PT image, but when I open the part in the 3D preview it looks Ok. And it also looks good on my screen until I turn on the prim substitution in LDView.
It's also looking good on a pov-ray image.
