I was playing a little in 7DS last night and made up a special ops ship (secret, cant tell you yet, but its an advent design on the blackhole generator that was found on Altairan, after the Vasari wiped out that colony, but then moved on. Refugees have been move in-system by the Advent and Tec, but the generator was uncovered by the Advent) 
I thought it would be nice to use a "different" model, as most of my "adjusted" ships now use current models, anyway, the mod-tool you mentioned Annatar, or the trial on 3dsmax that ShadowMastif mentioned sounds wonderful!
Perhaps i can make a ship, but then of course, i will have to learn how to import it into the game. But maybe importing isnt the problem though, so that would be nice. 
Thank you to everyone for the help!!
Sincerely,
