This rubric evaluates student portfolios for breadth in 3D design. It assesses investigation of design principles, originality of ideas, application of principles, intentions for space, technical skills, and personal voice. Higher scores require more thoughtful, original, skillful work that engages viewers and demonstrates a range of insights and accomplishments. Lower scores are for work that shows little investigation, originality, skills, or transformation by the student. The highest level of excellence requires confident, evocative work that clearly activates space through personal vision.
