Evaluation of Drawing Ability Based on Radar Chart

Assessing the studentspsila drawing ability is a chief content which is used for evaluating the relative quality of engineering graphics training. The goal of the investigation is to assess the studentspsila drawing ability accurately and visually. Radar chart which is mapping of evaluation factor is used as a diagrammatic representation to assess studentspsila drawing ability. In order to get the priority of evaluation factor, analytic hierarchy process is adopted and the hierarchy of drawing ability is developed. Then the circle of radar chart is marked off in accordance with the priority above. Further more characteristic elements of radar chart are used to evaluate drawing ability quantificationally. The examples demonstrate that use radar chart to assess drawing ability is feasible, it is not only intuitionistic and visual, but also can get quantitative value of drawing ability.
