Levels of Detail (Adjectives): The ship design process is characterized by progressive development of definition detail over the course of several years. To represent this consistently, our team developed a “shorthand” to allow quick but explicit reference to the level of definition resulting from any particular “definition” activity. This is also useful for quickly characterizing the extent of definition input information necessary before certain applications can be executed. Thus, we adopted a careful vocabulary on levels of detail. The vocabulary varied across three levels of ship design (Shape, Structure, and Systems), and in each provided appropriate levels of detail, extracted from design experience (e.g., Parametric, 3/2.5D Sufaces/Arrangements Reservations, Manufacturing Detail, Maintenance Detail, etc.). Complete discussion is not included here for the sake of brevity.
