理工科学生与艺术类学生相比,他们有着较强的学习能力和较高的综合素质。但是,相对艺术类学生他们审美性差、艺术功底薄弱、创新思维不够活跃。使得理工科学生对手绘效果图重视程度不够,更倾向于计算机辅助设计,忽视了手绘效果图在设计中的重要性。本文通过对手绘效果图的特点和重要性的分析,表明了手绘效果图作为设计师来表达设计思维的主要手段。手绘效果图的训练在提高理工科学生审美能力的重要意义。 Science and engineering students compared with art students, they have a strong learning ability and high overall quality. However, compared with art students, they have poor aesthetic qualities, weak artistic skills, and less creative thinking. Making science and engineering students hand-painted renderings emphasis is not enough, more inclined to computer-aided design, neglected the importance of hand-drawn renderings in the design. Through the analysis of the characteristics and importance of hand-drawn renderings, this paper shows that hand-drawn renderings as the main means of designers to express their design thinking. The training of hand-drawn renderings is of great significance in improving the aesthetic ability of science and engineering students.
