AutoCAD P&ID 2016
AutoCAD P&ID is the best program on the market for creating and documenting your 2D and 3D piping and instrumentation designs. Autodesk AutoCAD P&ID 2016 is more object-oriented compared to standard AutoCAD, so you get a smarter program while still working in the familiar AutoCAD environment.
AutoCAD P&ID allows you to produce your instrumentation and process diagrams more quickly, easily and efficiently.
As of April 2017 AutoCAD P&ID ceased to be a separate title of Plant Design Suite Standard 2018 and Architecture, Engineering & Construction Collection 2018. However, the AutoCAD P&ID functionality is still available in AutoCAD Plant 3D and, as such, is available in Plant Design Suites Premium 2018 and Ultimate 2018 and in Architecture, Engineering & Construction Collection 2018.
This is the only way, in the new licensing structure, to "buy" AutoCAD P&ID 2016 (further information on licensing).
