In general, a title block contains placeholders for 2 types of information:
When you add a sheet to a project, the project-specific information in the title block displays the appropriate information. You can enter the sheet-specific information directly on the sheet.
Revit provides default title block families. These title blocks include some project-specific information fields and some sheet-specific information fields. If you want to add more information (custom fields) to a title block, use shared parameters.
To add custom fields to a title block

Settings panel
(Project Information) to display the shared parameters that belong to the Project Information category. You can change these values in that dialog or on a sheet. Whenever you change project-specific information, Revit updates all sheets in the project with the changes. See Entering Project-Specific Information.
