To Edit an Existing P&ID to Plant 3D Mapping

1. In the Project Setup tree view, expand Plant 3D DWG Settings. Click P&ID Object Mapping.
2. On the P&ID Object Mapping pane, do the following:
   • Under P&ID Classes, expand the tree and click the desired P&ID object (for example, Gate Valve).
   • Under Plant 3D Classes, in the Plant 3D Class Mappings list, click the current mapping (for example, Valve (Gate-Inline, Gate-Angle, Gate-3-Way)).
     
   • Click Edit.
3. In the Select Plant 3D Class Mapping dialog box, do the following:
   • Under Plant 3D Classes, expand the tree. Click a class (for example, Valve).
   • Select the Map to All Subtypes of This Class check box, or under Map To One or More Specific Subtypes of This Class, select or clear the appropriate check boxes.
     
   • Click OK.
4. In the P&ID Object Mapping pane, under Plant 3D Classes, the Property Mapping table displays individual icons. These icons indicate whether a property is in acquired mode or override mode. In the Plant 3D Property column, do the following:
   • For properties in override mode
     1. From dropdown list, choose the appropriate value for mapping.
     2. Alt+click to reset all properties to acquired mode.
   • For properties in acquired mode
     1. Click the icon to switch to override mode before editing the mapping.
     2. Alt+click to override all properties.
   
5. To manage the validation process for the property mappings of a mapped item, select or clear the Check This Item During 3D To PID Validation option.

   Selecting the check box enables validation, while clearing it sets the validation process to ignore the property mappings of the item.

6. Click OK.
