CAD tip # 5510:

You can easily make your own symbol catalogs. Just open your drawing containing the blocks (with symbols) in AutoCAD and use the PUBLISH command to convert it to a DWF file. Such "library" DWF file can be then loaded in Design Review with the command "Import DWF as Symbol Catalog" (under the stamp icon).

1. In the AutoCAD's Publish dialog select just the Model sheet of your catalog DWG drawing (with inserted blocks).
2. With the "Publish options" button start the options dialog and in the "DWF data options" field set the "Block information" value to: Include.
3. Create a new "Block template file" (the next line).
4. In the dialog "Publish block template" click the "Scan for Blocks" button and then confirm the blocks (and their properties) for publishing (use the "Name" property).
5. Confirm the Publishing options (OK).
6. Start the DWF publishing with the Publish button.
7. Load the resulting DWF file into Design Review ("Import catalog" under the "stamp" tool).
