Abstract: This paper introduces 3D CAD modelling technology in engineering graphics#br# teaching in order to solve the problem that the students' spatial imagination and logical thinking#br# ability is not strong in projection theory teaching. As a new teaching idea, auxiliary teaching with#br# 3D CAD modelling technology can realize students' thinking transformation process of#br# 〝plane-space-plane〞, by adopting the modern teaching means. That is to imagine the shape of#br# the three-dimensional space body by the flat view and then express graphically the body through#br# the view form. Practices have proven that the organic integration of 3D CAD and engineering#br# drawings can not only improve the students? abilities of space imagination and configuration, but#br# also enhance their graphics conceptions.#br# Key words: engineering graphics; three-dimensional CAD modeling; graphics conception;#br# configuration ability
摘要： 针对工程制图投影理论学习中学生空间想象力与空间逻辑思维能力不强
的问题，将三维CAD 造型技术适时地引入到教学内容中。作为一个新的教学理念，采用现
代化的教学手段，用三维CAD 造型技术辅助工程制图教学，帮助学生实现“平面-空间-平面”
这一过程的思维转换，即由平面视图想象三维空间形体的形状再将形体通过视图形式来图解
表达。实践证明，三维CAD 与工程制图的有机融合可以提高学生的空间想象力与构型能力，
并能培养图学意识。
