If you have already installed the Blocks plugin on your computer, it will appear in Revit under the "Add-ins" tab. In the Portuguese version of Revit, this tab is called "Suplementos," and in the Spanish version, it is called "Complementos."
The plugin is named "Blocks" and can be found within "Interior Design."
Important: The plugin will not appear in Revit versions with which it is not compatible. Check the compatible versions in our FAQ.
