The following features and updates have been included in the Autodesk® AutoCAD® Plant 3D 2017.1 Update release.
Spec Driven P&ID - The Spec Driven P&ID feature allows the P&ID to lookup/reference the Plant 3D Spec files so that a P&ID drafter will know if objects in their P&ID are "in spec" (found in the pipe spec) or "out of spec" (aka "off spec" - not found in the pipe spec). For more information, see Workflow: Spec Driven P&ID.
