Thanks Michael. I really appreciate the response. Well that makes a lot more sense now. I wrongly assumed there was a bit more of a disconnect between how the Mesh generation "sees" the geometry and the underlying MoI modelling process. I guess there are a few MoI processes that would end up with holes in surfaces (like shells, insets, etc.). Though knowing that, it makes sense why the output is typically so great with complex things and now I have a way better way to look at things. Just gotta get out of my engineer mindset that keeps thinking of cutting holes when modelling hard surface things ;)
