Map P&ID Content to Revit Content

To facilitate modeling a P&ID drawing in Revit, you'll need to map P&ID components and schematic lines to real-world 3D model components, such as a P&ID valve symbol with a Revit family, such as a ball valve.

Note: The valve type name is used for size mapping. As a result, if you rename the valve type, the mapping status is updated. For example, if you rename “DN 100” to “100 DN”, a size mismatch occurs.

The following items should be mapped from AutoCAD P&ID to Revit.

AutoCAD P&ID	Revit
Piping Services	Pipe System Types
Pipe Line Segments	Pipe Types
Inline Assets	Pipe Accessory Families
Equipment	Equipment Families
Properties	Parameters

Video: Defining Settings

Use the P&ID Modeler Settings dialog to set up the mappings.

1. Click Systems tabCollaboration panel (P&ID Settings).
2. To map Piping Services in P&ID to System Types in Revit, click the Systems Type tab.

   When this mapping is established, the P&ID service assigned to a line will automatically set the Pipe System Type of the pipe when you create it. The P&ID Service list is from the selected P&ID project, and the System Type list is from the current Revit model.

3. To map Pipe Line Segments to Pipe Types, Inline Assets to Pipe Accessory Families, and Equipment to Equipment Families, click the Object Mapping tab.

   In the P&ID Class Name list is from the selected P&ID project, and the Revit Family is are those that are loaded into the current Revit model.

   Use the filter buttons to filter pipe accessories in the list. You can:

   • Show all unmapped objects
   • Show all hand valves and control valves
   • Show all pipe fittings
   • Show all piping specialty items
4. To map Properties in P&ID to Parameters in Revit, click the Property Mapping tab.
   You can assign which Revit shared parameter is populated with the value from the P&ID asset's Tag property.

   • Each shared parameter must be pre-defined in the Revit model as a shared project parameter.
     • See Create Shared Project Parameters.
   • When creating the shared project parameters, select Text for the Parameter Type.
   • The parameter for the Equipment category and Pipe Accessories category can be defined separately.
   • When defining the share parameter in the model, make sure to assign the shared parameter(s) to the appropriate category.
     • Assign the Mechanical Equipment category for the Equipment Tag P&ID Property.
     • Assign the Pipe Accessories category for the Accessory Tag P&ID Property.

In Revit, use Transfer Project Standards, to share settings between P&ID and Revit. P&ID Settings is listed in the Select Items to Copy dialog.
