Intergration with other software

Hi,

I'm prodding my department into investing in better software. I was looking at Solidworks and COMSOL, but it's possible that Altair's product might be a better. I'm wondering what the output/input file extensions are because I would like to integrate with STK. We also commonly import files for COTS parts.

When I looked up the extension, it looked like it was unique. Is there an option to save or import other types of files?

Thanks,

Nathan
