| 但愿没有各大机械学院的学生发现这个文档吧...否则的话整个任务的工作量就只剩一半了（这课就废了） 3 | 机械设计课程设计任务，python的pyautocad包。使用时在主文件dataall里设置好前面算好的参数，然后直接运行即可。由于下周四就要交作业了，还没画完，改用手画了。 4 | 完全放弃代码效率，只为了实现自动化。而且对于个人而言能把它画完就已经很要命了。代码工程量大约一百小时左右，两三周有空就在画。pyautocad调用了cad的原码库但是我找不到，所以只使用了画线画圆画点的功能。为了增加圆角和样条曲线而添加了文档arc和spl，运行主程序结束后点开复制到命令行即可画出圆弧。 5 | 因为没有线面操作，所以线性调整，剖面线等工作记录在categoryone中，出图后逐条修改即可。 6 | 各文档说明 7 | dataall：主文件，打开CAD后新建一张图，然后再开python运行这个文件就能画图。 8 | d_l：画线 9 | d_c：画圆 10 | d_pointline：带端点的线 11 | d_groove：有一个开口的矩形，以上都是为了画图方便，快一点 12 |
