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.

 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

Use the P&ID Modeler Settings dialog to set up the mappings. 
- Click Systems tab
Collaboration panel
 (P&ID Settings). 
   
- 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. 
	 
 
   
- 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 
		
 
 
	  
 
   
Note:  Pipe Accessory Family type names are used for size mapping.
	 
-  The type name of the mapped family in 
		  Revit must start with the same value as specified for the size of the element in AutoCAD P&ID. 
		  
 For example, "100 DN - Threaded" is a valid type name to match to a P&ID element with a size of "100 DN", however, "DN 100" is not. 
		  
 
		 
-  The size value must begin with a numeric value in order for it to be associated with the numerical size parameter. 
		  
 For example, "100 DN" is a valid size in P&ID, however something with the size "DN 100" will not be able to be mapped in 
			 Revit.
		  
 
		 
 
   
- 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. 
		  
 
		
 
- 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.
