机械类工程图学课程教学体系的重构与思考

Reconstruction of Teaching System of Modern Engineering Graphics for Machinery Speciality

简述了工程图学在我国的发展历程,指出现代工程图学的特点与发展趋势以及现代工程图学教学中的问题与不足。由此提出构建机械类专业工程制图课程由传统的以手工绘图技术、读图能力训练为主向以读图和计算机绘图能力训练为主转变的新型教学体系(亦称2D3D模式),并对具体的课时分配及实施措施提出意见和建议。

The present paper describes the developing history of Engineering Graphics(EG)from the be-gin ning to present ,and some characteristics and shortcomings are pointed out in modern EG teaching first.The modern EG consists of De scriptive Geometry,Mechanical Drawing,Mod elling Design and CAD that are different from the traditional courses of drawings.Author thinks that the ability training for read-ing drawing is of great importance to students,and a good grasp of the mechanical drawings standards and basic knowl edge of Descriptive Geometry of CAD software use are also important to future engineer-ing staff.A new teaching mode stressed training the space imagination from3D to2D and2D to3D by means of solid and other tools is given.
