ObjectARX applications can be loaded as part of a plug-in using a package format, which is a common folder structure with a .bundle extension. Each package can contain the files required to deploy an application and register the commands contained in the application. A package is loaded into AutoCAD by placing it in one of the ApplicationPlugins folders on your local drive.
The APPAUTOLOAD system variable controls when AutoCAD looks in and loads the plug-ins from the ApplicationPlugins folders. If APPAUTOLOAD is set to 0, plug-ins can be loaded using the APPAUTOLOADER command.
For information on deploying an application with the package format, see “Install and Uninstall Plug-In Applications“ in the Customization Guide.
