To correct P&ID validation errors

1. Validate the drawing or project.
   
2. In the Validation Summary window, do any of the following:
   • To zoom to the error in the drawing, click the error. You can then fix the problem manually.

     Note: To change the status of an ignored error, in the Errors Marked as Ignored folder, right-click the error node. Click <Unassigned>.
3. To validate the drawing for this error again, in the Validation Errors tree, right-click the Base AutoCAD Object folder. Click Refresh.
