Hi Michael

I use MOI3D a lot for cleaning up and meshing IGES files to ready for rendering in LightWave3D.

The biggest headache I encounter all the time are flipped surfaces, where the original modeler hasn't bothered to make sure all the surfaces are facing the 'correct' direction. I can flip the offending meshed polygons in LightWave after import, but often, editing surfaces in MOI3D is much quicker and easier.

Clearly I can use MOI3D's flip command, but the problem is I have no idea which surfaces need flipping because they are double-sided shaded. Is there anyway to get MOI3D to show or preview the surfaces as single-sided as they might appear when meshed?

Ideally, it would be awesome if there was a surface direction repair tool that could eliminate these issues with imported IGES files, then my world would be complete! :)

Other than that, MOI3D is such an awesome tool in my armoury!

Cheers
Matt
