求改画侧螺纹孔的源码
本帖最后由 669423907 于 2012-3-3 20:48 编辑不知在去年什么时候下的画侧螺纹孔源码，源码很累赘，自己看了好都没改成，希望大师们帮忙精简一下，在此先谢过了！
1：不要改变基点
2：只留虚线层和中心线层

哪位大师高抬贵手，帮帮忙啦，实在不会改啊1 langjs 发表于 2012-3-3 20:46 static/image/common/back.gif
这个问题还要求助啊？自己看看书就能修改了，都是基础的，只是时间问题。我也要几个小时才能把坐标点对出来 ...

langjs 大师，“3中心线” 层我改好了，但改不出 “2虚线” ，
我想用 “2虚线” 层做为螺纹部分，但不起作用？
还望 langjs 大师明点！
