I noticed the below sentence (bold by me) in the press release from AVEVA.
Bruce Douglas, Vice President Industry Solutions at AVEVA said "Our approach is to provide the maximum choice in the selection of engineering authoring tools. The open approach means that P&ID data can be uploaded to the AVEVA Schematic Model from any P&ID system that can deliver P&ID data in the ISO 15926 format. Currently supported P&ID formats are: AVEVA VPE P&ID; AVEVA P&ID Designer; Smartplant P&ID. AVEVA P&ID Designer, jointly developed with Autodesk, is based on AutoCAD P&ID".
There is no question that BIM is the future but AutoCAD has its place as platform for AutoCAD P&ID as well as AVEVA P&ID Designer. Yes, Piping & Instrumentation Drawings (P&IDs) are part of BIM in the process industry.
