Concept vs Technical
Orthographic Projection (One View, Multiviews)
Pictorial (Isometric, Oblique, Perspective)
Poor / Failing

Draftsman/Engineer failed to communicate necessary information to viewers due to missing views, missing details and/or missing annotations. There is no evidence of the knowledge of industrially acceptable sketch types or views Nor the criteria for choosing an appropriate representation.
Minimal / Needs Improvement

Basic

Draftsman/Engineer comprehended the information needed to be communicated, however the chosen sketch style and views failed to include all the necessary information to viewers. Sketch style is industrially acceptable, however better choices for Views selected or Number of views could have improved viewer's ability to obtain information necessary to accomplish stated goals.
Proficient

Draftsman/Engineer comprehended the information needed to be communicated through the sketch and correctly created the appropriate sketch type. Better choices for Views selected or Number of views could have improved viewer's ability to obtain information necessary to accomplish stated goals.
Distinguished

Draftsman/Engineer fully comprehended the information needed to be communicated through the sketch and correctly created the appropriate sketch type & Number of views. Viewers of the sketch have no difficulty obtaining information necessary to accomplish stated goals.
