Hi Andrew,

re:
> Thanks Michael. Do you have any idea why the STL file would export properly?

It could be that it's not actually damaged and it's instead a glitch in the display mesher. When you go to do an STL file export, MoI uses a different meshing engine which is more thorough in how it processes things - the display mesher takes some shortcuts for certain things in order to gain speed. Maybe one of those shortcuts is not getting along well with the type of shape there where the top planar face pointy areas.
