This is very likely, though really alot of modelling/3d Animation software all had similar roots, just change a few names of tools/processes/filters and whammo. 
I started out with 3DSMAX, an allrounder program, that did everything okay, but nothing great (light filters were very good at the time around build 7) while Maya is a far better modelling software, and also better for large polygon rendering (lots of items, or detail).
Commercial programs are a different breed to a modelling software (due to the emphasis on being able to manipulate and change the models... so your best bet is to just get a program ans start playing around on it.
