I know if i use step or iges i can save them and open with 2013, but they some of the parts dont show up right.

what is the best file format to save as to have sw 2013 recognize most of the parts?

i renewed my subscription for 2014, but not for flow simulation, but i think my flow sim 2013 still works, so i need to work in 2014 and open it back up in 2014 to do flow sim.

argh.

any input is appreciated,
