Add-In Integration
Developers add functionality by creating and implementing External Commands and External Applications. Revit identifies the new commands and applications using .addin manifest files.
- External Commands appear under the External Tools menu-button on the Add-Ins tab.
- External Applications are invoked when Revit starts up and unloaded when Revit shuts down
This chapter focuses on the following:
- Learning how to add functionality using External Commands and External Applications.
- How to access Revit events.
- How to customize the Revit UI.
