OK, thanks for the info. I downloaded the ViaCAD demo version and the interface is ... challenged, I guess is the way to put it. Every time I have to use it, I predict I will be irritated. :P

So is there a best practices for Filleting thread somewhere that I could read through or is it just an experience thing? The more I can stay in MoI, the better, so even if I have to change the way I build certain shapes it would be better than trying to juggle multiple apps.
