Auxiliary 3D Calculation of Traverses under CAD Environment

A method to implenment the coordinates and height adjustment simultaneously by using the powerful drawing function of CAD is introduced in this paper. Some differences between auxiliary 3D-CAD compulation and 2D-CAD one and their practicality are provided. Experiment proved that the method has advantages such as simple and quick in computation, high visuality, and convenient in inquiry. The method can trarsform the traverse computation from a formula program to a precise drawing process and the results of traverse computation may be achieved upon inquiry. The method is superior to 2D-CAD traverse computation, so it is worth popularizing.
