Add-ins are software programs that provide additional functionality for Autodesk software.
Some add-ins are provided to Autodesk subscribers. Other add-ins are available free of charge or can be purchased from a third-party vendor.
When you create a Revit deployment, you can include add-ins as part of the deployment so they are installed on target computers with the Revit software.
You can use command line options to control how an add-in is installed, which may be useful when scripting for automation. The options that are available depend on the method used to install the add-in.
When you start Revit, the Add-in tab displays between the Manage tab and the Modify tab.
If you encounter problems with the add-in installation, go to the Revit user forum for help.
For these Autodesk-provided add-ins, you can use the options that are available when installing Revit from the command line. See Options and Parameters for the Revit Installation Command Line.
