FEMAP W/ NX Nastran Conversion into Solidworks

I have a coworker that creates models using the above mentioned software. I personally know nothing about its functionality. What I do know is he exports out the assembly models as step files and it creates a single files for every part (meaning if the same part is used 12x, 12 different file named parts) and each is a dumb solid.

I end up recreating each part with features and smarts.

My question is if anyone knows if there is a setting within his software that would allow these models to export a little more cleanly.
