Guardian Glass for BIM reads orientations from the True North setting in the project. If Project North is rotated for ease of modeling, the application will continue to provide correct orientations. Rotation may be deduced if the view cube and compass in Revit do not align (Front usually aligns with South – if no rotation has occurred). True North setting may also be reviewed in the Project Location menu under the Manage Tab in Revit.
True North may be set (once you are in a Plan View in Revit) under the Manage Tab – Project Location – Position.
