工程图学立体化教材建设的研究与实践

Research and Practice of Engineering Graphics Stereoscopic Textbook Construction

文章介绍了工程制图立体化教材的建设思路、内容和特点,提出一种用计算机三维造型更新传统画法几何的教学体系,用"构型要素—立体—投影图"的思维模式,取代原画法几何"立体—投影图"的思维模式,用构型要素、布尔运算等现代设计思路分析基本几何体、组合体、剖视图、零件图等的画图、看图,拓宽了学生思路,化解了学习难点。教材的配套多媒体辅助教学系统中开发的"零部件拆装和测绘"和"构型设计乐园"等内容,丰富了教学环节和教学手段的多样性,提高了工程图学课程的教学质量。

This paper introduced the Engineering Drawing three-dimensional thinking of building materials, content and features, proposed a system of traditional teaching descriptive geometry update with three-dimensional computer modeling, with"configuration elements-perspective-projection"mode of thinking, to replace the original painting law geometrical"perspective-projection"mode of thinking, with modern design ideas analyzes configuration elements, Boolean operations and other basic geometry, assembly, cross-sectional view, part drawings and other drawing, pictures, broaden the students' thinking, to resolve the difficulties in learning . Textbooks supporting multimedia assisted teaching system developed"parts disassembly and mapping"and"Configuration Design Paradise"and other content, enrich the diversity of teaching and teach-ing methods, improving the quality of teaching engineering graphics course.
