The most important thing I like about this system it's easy for users who are not familiar with technical aspects or IT background as well they can create models using their own drawings so there will be no need extra training at all time! If you want user friendly interface then its very good choice but if your looking forward in customization features than go ahead otherwise don't waste much money please. Creating BOMs and other related documents were made easier because we could use our favorite tool iMS Project which was integrated into soft expert plm suite!!
