机械制图中CAD 教学的软件选择与教学设计

针对机械制图中CAD 教学的学时短、内容多等问题，采用精简教学内容，注重实际操作的融合式教学法具有较好的效果；综合比较了国内外二维绘图软件的功能与特性，在满足学校软硬件配置要求的前提下，提出教学软件除应具有应用广泛、通用性好、操作界面友好等性质外，还要能体现设计思想与表达形式相分离的先进设计理念。教学实践表明，恰当的软件选择和以动手能力为目标的CAD 教学方法能很好地满足学时和能力要求，拓展了学生的知识面。

The Selection of Software and Teaching Design for Course of CAD inMechanical Drawing

To solve the inconsistency between short periods and excessive teaching contents, anintegration teaching method of simplifying teaching contents and emphasizing practical operationsynchronously is proposed. The functions and characteristics of domestic and overseas 2D drawingsoftwares are studied synthetically. On the premise of satisfying the configuration request of softwareand hardware, the teaching software ought to be characteristic of wide application, easy adaptationand friendly operation interface so on. In addition, the view that teaching software should embody theadvanced idea of design thinking separating from expression format. The teaching practice shows thatthe CAD teaching method taking operation ability as goal can conform to the requirements of periodsand abilities. And the knowledge field of students can be spread.
