Thanks Michael. I will definitely update my progress. Creating a hull with MoI is just too easy. I could cry when I think about the countless hours I've wasted on creating polygonal hulls, even sds smoothed ones. I'm also *very* impressed with the quality of the boolean tools and the stability of the program. Not a single crash in the whole time I've been learning to use it. Impressive.
