Autoplant to PDS

Hey Guys,
How difficult is it to go from AutoPlant to PDS or PDMS? I know learning CAD software is not rocket science. I'm assuming if you know how to work in one 3D environment learning another should be a hell of alot easier than starting from scratch. Is that correct? Generally how hard is PDS or PDMS to learn.
Thanks guys

The conversion from AutoPLANT/REBIS/Bentley to AVEVA PDMS is not horrible but brings with its own set of chalanges. PDMS is not a AutoCAD or Microstation based product. It has its own modeling engine, draft engine and isometric engine all within its self. After using REBIS, Plant-4D, Pro-Pipe, and PDMS...PDMS is a far superior product for alot of reasons. It is 100% solid modeling not wireframe. It is 100% multi-user without "referecing" other drawings in just to see what is in the area. You spend more time modeling and less time "drafting". I can go on and on. Let me know if you want to know more about PDMS.

Also, We will be looking for designers in KC probably before the end of 2006. Send me PM and we can talk. We are will also be providing basic PDMS training as required.
