摘要
针对渐缩异径弯头展开图较难绘制的情况,提出一种新的计算绘制方法,通过解方程求交点确定空间线段坐标来求取其长度。此方法克服了"绘图法"操作困难、精度不够,常规"计算法"步骤繁琐、使用范围窄等缺点,可以实现高效精确的计算并为应用Autolisp程序自动绘图提供了方便。对于提高工作效率,推广渐缩异径弯头在实际工程中的应用具有积极意义。
As the fact that the unfolding of reducible elbow is very difficult, present a new method for unfolding reducible elbow. That is, through the equation get coordinates of the space line and obtain its length. This method has overcome the shortcoming of"method of drawing" and "method of calculation" , it will make the calculation more accurately and the autodraft of Autolisp more convenience. In view of the advantage of the new method, this article will be useful for improving work efficiency and popularizing the application of reducible elbow
