AutoCAD P&ID 2017
AutoCAD P&ID is the best program on the market for creating and documenting your 2D and 3D piping and instrumentation designs. 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 2017 (further information on licensing).
