图解法的CAD实现途径

The CAD Implementation of the Graphic Solution

传统图解法通常采用手工绘图解决空间几何问题,作图结果不精确。采用计算机辅助设计方法可以求解图解法中的度量、定位问题,通过建立空间几何元素的精确几何模型,利用AutoCAD软件的辅助设计功能得到空间几何问题的精确结果。

Conventional graphic solution was often manually used to solve the problem of the spatial geometry in Descriptive Geometry and thus the result is inaccurate. The paper introduces the CAD method to solve the metric and position problem in the graphic solution. The accurate result will be obtained by constructing the geometrical element model with the aid of the design function of the AutoCAD drafting software.
