AutoCAD Architecture 2023 toolset supports multiple keynote databases, which you can assign to individual projects. When you are working within a given project, only those databases assigned to that project are accessible through the Select Keynote dialog box.
Before a database can be assigned to a project, however, it must be on the list of available databases. Both keynote databases provided with the software (AecKeynotes and AecKeynotes-Assemblies) are included on this list by default. You can add databases to the list or remove them. If a particular keynote exists in multiple databases, you can specify the order in which the databases are searched to find a keynote that has been specified for an object. (Only the key is stored with the object style; the corresponding note must be retrieved from a database at the time of insertion.)
