I have been in Piping design for about 10 years, and working with AutoCAD plant 3d for past 5 years. I have implemented AutoCAD plant 3d for many of my clients, which include below, I can help you transform from non intelligent modeling phase into Intelligent modeling phase using AutoCAD plant 3d. I can also develop both P&ID's and 3D piping model in AutoCAD plant 3d, and generate required output from that, like P&ID's, Isometrics, Ortho views, Reports(Line list, Valve list, BOM, MTO, etc)
