Hi Michael,

I have noticed this inversion of normals, but not on such a full scale, and that was from a view point within MoI

I have seen this where I have made boolean, then I notice I can see through the model on some areas and I thought the model was broken, but on checking (using the select solids) did show the model as solid.

I have been trying to find a good ( simple) example of that.

I dont know if this is related?
