Yes, they do permit resale and the seller you pointed out have sold their license for a little more than I was hoping to pay. I've got 2 licenses already and for the little use I would have for a third means I have limited budget so hoping to get lucky here.

glad if my babbling is helpful.

FWIW, I also tend to minimize nesting as much as possible it generally makes it more complex to edit the model and it is easy to get nests screwed up. also make sure you have a clear understanding of layers and only make layer associations for components/groups. Leave Layer 0 active at all time, draw everything on Layer 0 and make sure edges and faces always remain on Layer 0.

Thanks Dave.
So far, Fredoscale seems to be behaving while avoiding groups.
