Effect of Fundamental Drewing Education for 2D Drawing though 3D Modeling

Abstract

In this study, we made hypothesis that, for creating 2-dimensional drawings eventually, it might bemore effective to teach basic drawing first, and then teach 3D Modeling using 3DCAD instead of teaching 3D Modeling from the beginning, and we conducted experimental teaching, having divided the students into two groups that receive different teaching methods. As a result, in creating modeling by 3DCAD, almost no differences of effects were observed in the 3D Modeling skills, such as modeling time required, and accuracy of modeling. On the other hand, in the 2-dimensional drawing creations that was the objective, although there was no difference observed in work time between the two groups, in whether they were able to create drawings with considerations of measurement allocations and such, , drawing educated group performed better than novice group. Moreover, in understanding level test, drawing educated group excelled as well. Today, basic drawing education is often omitted, and they teach drawing by using CAD from the beginning, but this study suggested that, although it would not affect the work time so much, it would greatly affect the quality of finished products. Therefore, we could conclude that the basic drawing education is necessary for teaching drawing by using CAD as well.
