Hello,

I'm still pretty new to Solidworks and its API, but I've already managed to write a code to import parasolid files and export them to a different format with a specified configuration, which is working great!

Now I'd like to do the same for lots of file and since I've noticed Solidworks doesn't seem to be multi threaded when loading a file (at least not a parasolid file), my first attempt was to create multiple Solidworks instances, each loading a new file and exporting it. Although this does solve my problem, I'm left with a few warning messages displaying something about another instance of Solidworks already running, which doesn't annoy me much. After some tests, this solution seems to be about 3x faster than a single instance/thread one.

With that solution I can run several instances of Solidworks on the background (up to 9 I think), with no UI at all. But, lets be honest, this is a terribly ugly solution.

Is it possible to solve this issue with a single instance of Solidworks and multiple threads? Perhaps creating several sessions and issuing the 'save as' command on different tasks? I didn't find much reference to multi threading on the forums or how to have multiple sessions on a single instance...

Also, if a single instance solution isn't possible, is there a way to suppress that warning message?

So, just to round up my question: Id like to write a code to import a bunch of parasolid files and convert them to STL, all in parallel and using a single instance of Solidworks. Is that possible?

Thank you all for your help! =)
