You can set the following scene preferences.
Scene coordinate system
Set or redefine the scene coordinate system. See Georeferencing.
Modifying the scene coordinate system will not reproject or relocate the data in the scene. It only redefines the internally stored reference system used for future data imports.
Show handles
This preference enables or disables handles in this scene. Handles are shown on the currently selected model, if the rule file was created with handles. See Handles.
