Hi all! We use Bentley's intelligent Autoplant P&ID, 3D, Piping, Equipment, and Data Management packages. I am in charge of the P&ID/data management. Though there is a steep learning curve, we benefit tremendously from the centralization of our data. Changes to line numbers are easily picked up and distributed throughout the various disciplines automatically. Its smooth, efficient, and separates us from our competitors. I would like to try PDS or PDMS (are they different?) and see how that all works. I heard the up front costs are astronomical. cheers
