摘要:本文以工程图学教学过程作为分析的对象，讨论了以三维数字模型方式，取代实际的模型，开展的绿色设计理念的实践活动，使工程图学教学过程更加生动、有趣的体现设计性。通过选择视图的投影方向和剖切位置，在不改变结构的情形下，自己确定尺寸大小，可以更好地培养学生们的绘图设计能力，也适应了当前大学本科教学中对工程图学的要求，受到学生的认可。这样的工程图学教学模式必将随着各种科学技术的进步，不断扩大其教学内涵。

Abstract: In this paper, the process of teaching engineering graphics as object of analysis is discussed that how to use 3D digital model and replace the actual model of green design concepts to carry out practical activities to make the teaching process drawing more lively, interesting manifestation of designing.By selecting projection direction and cutting the position of the view, without changing the structure of the case, to determine the size of their own, can better engage students in the graphics design capabilities and adapt to the current undergraduate teaching university requirements for engineering drawing by student recognition. This teaching model will progress with a variety of science technology and expand the teaching contents Engineering Graphics.
