【摘要】 培养学生阅读组合体视图能力是工程图学教学的重要内容之一,运用AutoCAD的多视窗同时显示二维视图及其三维模型,并在三维模型窗口根据形体分析过程动态演示组合体分解与组合过程,加强学生的构图和读图能力。动态演示的AutoLISP程序使用方便可靠,交互式处理便于教师灵活掌握讲课节奏,发挥更佳效果。更多还原

【Abstract】 To develop students’ ability of reading composite solid is an important task in engineering graphics. The AutoCAD windows show two-dimensional engineering drawings and three-dimensional models at the same time, and demonstrate the composite solid decomposition and combination processes according to the shape analysis with three-dimensional model window, strengthen the students reading ability. The AutoLISP procedure of dynamic demonstration goes reliable and operates easily, interactive program makes it easier for teachers to give flexible arrangement in classes and get better result.更多还原
