The 3dx solutions for “PDM/PLM” which is basically what you are referring to I believe is limited exclusively to the cloud version of Enovia.
I have not been an Enovia user, but my feeling is that, while it is very professional and seems to work well, it is also extremely rigid and “one-size-fits-all”. My brother has hands on experience with Enovia and he agrees with that statement.
Even Dassault agrees. (here’s one of the slides from a 3dx world presentation)
My feeling based entirely on thin air is that Enovia was built specifically by an aerospace company for an aerospace company. The eco-ecn and change management appears to be built very top down with a focus on approvals and a high level of auditability at all stages. When we were pitched Enovia at our last pdm/plm crossroad the salespeople were not able to show us a valid implementation of Enovia that worked with our business that would not introduce a huge bottle neck that didn’t already exist. (that said maybe they weren’t the greatest sales people) If your business model more closely resembles the model that enovia was built for, I think you could do very well, but if not, it could be a nightmare.
