This command reviews any component in the model requiring reconstruction, replacement, or update as a result of changes to the Reference Database.

This command makes extensive use of data provided by the Reference Data Managers revision management reports. Refer to the Reference Data Manager Reference Guide for more information regarding these reports.

You can review all pertinent information regarding the revision management reports for the Reference Database on the basis of the following error types.

  • a dimension table has been revised

    Use the Reconstruct Component command with this component.

  • a weight table has been revised

    Use the Update from Reference Database command with this component.

  • a discrepancy between the specification data in the model and that in the Reference Database

    Use either the Reconstruct Component or the Update from Reference Database command with this component on the basis of which specification data has a discrepancy.

  • the specification data for a component in the model is missing from the Reference Database; it has been deleted from the Reference Database

    Delete this component and replace it with a different component or add this component to the Reference Database.

Although a component might be reported through more than one Reference Database Revision Management report as having data which is inconsistent with the Reference Database, the component will only be reported for review once by this command. Only the most severe discrepancy is reported using the following prioritized list.

  1. The specification data for a component in the model is missing (has been deleted) from the Reference Database.

  2. A dimension table has been revised.

  3. A discrepancy between the specification data in the model and that in the Reference Database.

  4. A weight table has been revised.

Update Component from RDB – This option automatically revises the component in the model without exiting the command. The system reconstructs the active component or updates its data from the reference database on the basis of the type of error and the data involved. Once the component has been revised successfully, it will no longer be reported. The system also performs the following items where applicable:

Design Checker is automatically activated at the end of each end of any component or pipe that is being reconstructed. Design Checker is not activated for non-geometric data that is updated on the basis of changes to the reference database.

If required as a result of a change to the fabrication category from the Reference Database, the weld type is updated at each welded end of the component or pipe being reconstructed or updated. It is no longer necessary to remember to correct the weld data that results from updating the fabrication category of a component or pipe being reconstructed or updated at a welded joint when you have a Weld Type Table loaded.

If the Weld Type Table is loaded, the system defines the weld type using the Weld Type Table. A Weld Type Table is delivered in win32app\ingr\pddata\sample\data called weld.tbl. A sample of the data that it contains is shown below.

If a Weld Type Table has not been defined for the project, the weld type is revised to the default weld type value, 'shop weld' (11).

If you set the toggle on the Revise Weld Type form to Respect Weld Type by User, the weld type is not revised for either the welded end of the component or pipe being reconstructed or updated or the corresponding welded end of the other component. Also, the weld type is not revised when the mating welded end is not in the active piping model, since you do not have write access to reference models.

When the system defines the weld type, the following considerations are made:

  • The system uses the Weld Type Table to determine the weld type on the basis of the fabrication category for the component or pipe being reconstructed or updated and the other component at the welded joint.

  • If the weld type of the other component at the welded joint differs from the one determined by the project's Weld Type Table, the weld type of the applicable end of that component is updated to the same weld type as that of the end of the component or pipe being reconstructed or updated on the basis of the Weld Type Table.

The Report Date field represents the most recent date for which a discrepancy was reported for that component involving the component's data in the model and the corresponding reference data. This date will not necessarily be the date the specific discrepancy was reported or the date of the most recent revision management report.

The Discrepancy field indicates the type of error. For all components, regardless of the type of discrepancy reported, the system indicates if the component requires reconstruction as a result of changes to piping segment data in the model, such as piping materials class or nominal piping diameter. This might save you from needlessly updating the component's data from the Reference Database when other revision management facilities would indicate that reconstruction is required. For example, a component might be reported as only requiring updating as a result of revisions to the Reference Database, whereas that same component might require reconstruction as a result of changes in the model.

You can select the right arrow to display the next discrepancy. The components being reviewed are sorted by line id.

If you must exit this command to make related revisions in the model or for any other reason and then re-enter this command for analysis purposes, the next component in the revision management is displayed automatically.
