COE which is an acronym for a U.S. Community Of Experts of Dassault Systemes products. The conference offers an in-person opportunity to connect with fellow users and share insights on similar business challenges. You really don't need to be an expert to attend, but you will get a up-close look at the latest products and technologies, evaluate your relative applicability for emerging needs and learn how to implement valuable solutions through hands-on labs and sessions from other expert users.
If you missed the last COE in New Orleans and want to get a glimpse of what it was like, feel free to take a peek.
