摘要
画法几何中通常采用手工绘制展开图,作图结果不精确。这里介绍了参数法绘制可展曲面的推导过程,并在AutoCAD2004软件上编程验证了参数展开的有效性。该方法可用于扩展计算机图形软件的曲面展开算法。
We could not obtain the higher required precision if we manually expand the developable surface. The paper demonstrate the way using parametric expansion method to draw the developing drawing and verify the effectiveness using programming method on the computer . The algorithm can be applied on the field of computer - aided drafting on the surface development.
