TPC knows which traverses were created from Point Codes and can update these traverses, adding any points with the appropriate point codes that were not included when the traverse was created. You would use this command if you were adding data to an existing site survey and wanted to make sure that you had all the catch basin points in the catch basin traverse and all the utility pole points in the utility pole traverse, etc.
If one or more selected traverses don't have a Point Code associated with them, TPC will issue a warning to let you know.
