We use SolidWorks Enterprise PDM and have a partner company that uses PTC Windchill. We are starting a collaborative project and we are looking at the best way to share SolidWorks files. There are a couple of options that we have on the table but I wanted to ask if anyone has integrated Enterprise PDM with Windchill as this is the option we would like to go with. Some of the challenges that we see are linking the databases, the notifications when the state changes, and moving files between the two PDM systems. Has anyone done this? Is it possible? Will this make upgrades down the road impossible due to the additional complexity?
