There is a session scheduled for SolidWorks World 2012 called "Enterprising EPDM with Web Services" given by Frank Pampreen. The write up sounds like it would be helpful to you. Will you be attending the conference?
EPDM 2011 SP2
I really wish i could make it this year, last year was a blast.
But, alas, I cant this year. I am hoping it will be one of the sessions that they post the whole presentation. Otherwise I am hoping that our VAR comes through with something.
