What must a group be converted to in order to be edited outside of the current project?

To edit a group outside of the current project in Revit, it must be converted to a link. Linking a group allows it to be referenced and edited in a separate Revit file. This method provides several advantages, including maintaining the original project file's integrity and enabling collaborative work. By converting a group to a linked file, users can make modifications to the linked file independently, and any updates made to it can be easily reloaded into the original project.

It is important to note that while families and libraries may be suitable for certain design elements, they do not explicitly allow for the same editing capabilities as a linked file does when it comes to groups. Similarly, CAD formats cannot be directly edited in the same way as a Revit file. Converting a group to a linked file ensures that the dynamic relationship and collaborative capacity are preserved while allowing for independent editing.
