Reference ratings are used to provide a measurement aid with custom reference alternatives when specifying ratings. For general information on rulers, see the section on working with rulers.
In Tetra GDM reference ratings can only be created by the model owner. However, all decision makers can view and use the model's reference ratings.
Operations to rename, delete, edit properties, cut and copy reference ratings are identical to those for rating rulers. Only the paste operation differs, as reference ratings can only be pasted in the Reference Ratings folder. See Working with Rating Rulers.
