3D Pipe Design Software

I work for a small consulting design firm. We specialize in water and wastewater treatment plant design, specifically microfiltration and reverse osmosis systems. Currently, we (the 2 piping designers) do all our plant design drawings in 2D, AutoCAD 2000i. Our plant designs use Stainless Steel, Carbon Steel, PVC, CPVC, and FRP piping. We need a software program that is compatible with AutoCAD, and need the ability to share 2D files with other design firms. I am seeking information from users of 3D software programs, who can tell us what they like and don't like about the software they use. Thanks! Received on Wed Apr 21 19:05:00 2004
