In addition to using catalog items from the CONNECTED project, you can also create your own catalog item and publish it on the cloud so that other project users can consume it. The general workflow for publishing your own catalogs is as follows:

1. In a DGN file, download the catalog item type library that you want to attach to the new catalog.
2. Create a model that you want to include in the catalog item.
3. Attach the item type to the model. The attached item type contains fixed set of properties that all models uploaded as catalog items should include.
4. Publish the catalog item.

For more information on item types and item type libraries, refer to the section Item Types.
