AutoCAD P&ID limitations
Following are known problems related to AutoCAD P&ID:
Opening or saving files to an Meridian Enterprise vault with AMFS enabled can generate the error "Drawing file is write protected" if the Meridian Enterprise client, EDM Server, and AMFS service are all on the same computer. The error does not occur when Local Workspace is enabled.
The AutoManager File System (AMFS) does not work (vault drive mappings are inaccessible and folder contents invisible) after saving a drawing from AutoCAD P&ID, while AutoCAD P&ID is still open, and if the Meridian Enterprise client and server are running on the same computer.
An unhandled exception can occur after viewing a project's properties from an Meridian Enterprise vault with AMFS enabled. Restart AutoCAD P&ID to reopen the project.
