Fast Track Plant
By using the Fast Track Plant app, you will be able to modify AutoCAD® P&ID tools more quickly, and model in AutoCAD® Plant 3D more efficiently. P&ID Tools include, among other things, picking spec driven valves and properties, removing blank insulation from line tags, and moving individual attributes. In the 3D model, a line isolation palette is included to help you isolate lines by line number and across drawings. Routing tools are also included to help routing within pipe racks.
