Exporting to an RP File
To export a shared project to an RP file, open the shared project and use File->Export Shared Project to File in the main menu. Once exported, the RP file can be opened and edited as usual, but will no longer be connected to shared project.
To incorporate changes made in an RP file to a shared project, open the shared project and use File->Import. This will allow you to import pages, masters, and project properties from the file to the shared project. Note that the pages (or masters, etc.) must be checked out in the shared project if you are replacing those pages with imported pages.
