To Validate the Parts in a Catalog

You validate parts that you have changed or added to a part catalog. Only validated parts are available during part selection.

To validate the parts in a catalog

1. Verify that the catalog you modified is one of the catalogs specified on the MEP Catalogs tab of the Options dialog box.

   Only the catalogs specified on this tab are loaded into the drawing and, therefore, can be validated.

2. In AutoCAD MEP 2025 toolset, click Manage tabMEP Content panelTest Catalog.
3. Note the prompt on the AutoCAD MEP 2025 toolset command line: Catalog Test [Cabletray/Conduit/Duct/Mvpart/Pipe/All]
4. Specify the catalogs to validate:

   If you want to validate ...	Then ...
   all of the catalogs	enter a (All), and press Enter.
   the catalogs specified for a single domain, such as Duct or MvPart	enter the appropriate letter, and press Enter. (For example, to validate the catalogs specified for Duct, enter d.)

   During the validation process, the software steps through the catalog structure and validates part sizes by verifying the existence of the necessary part size information. For example, it checks that parameters for AoD (angle of deflection), CEL (connection engagement length) are present. It also tests conduit content that includes the nominal size property. Any such content without nominal size will not pass.

   When the catalog test is complete, a dialog box containing the results is displayed. As noted in the dialog box, you can view the full test results in Validate\Catalog_Validation_Summary.htm; the Validate directory is located in the same directory as the Autodesk part catalog (APC file).

5. Click OK, and press Enter to end the command.

If any errors were found, you can fix them by opening the catalog in the Catalog Editor, navigating to the part, and editing the part data.
