I think I saw a mention of MoI over in the Strata3D forum. I had been looking for a solid modeler to compliment Strata's poly modeling tools and eventually settled on ViaCAD. Shortly after purchasing that I found MoI. Having an art, rather than an engineering background, I wish I had found MoI first. Michael has certainly captured lightening in a bottle with MoI!

ViaCAD still comes in handy for some of the trickier shell and fillets...
