In the current version of cadett ELSA, the drawing classes, drawing types and project related drawing types, have all been replaced with the much more general term "document codes". One possible use of document codes is according to the old drawing classes and drawing types, which are currently referred to as *LEGACY*. This means that the current technology is fully compatible with old projects using drawing classes and drawing types.

The table below describes the Class/types *LEGACY* document code tree used in cadett ELSA projects with old settings.
