源代码有点问题，详见后面的回贴
感谢楼主无私奉献！
输入什么命令运行？ xhq1954425 发表于 2014-6-13 20:42 static/image/common/back.gif

好酷哦，谢谢你！ 本帖最后由 xhq1954425 于 2014-6-14 10:35 编辑
这么多下载的连个回复都没有？怎么能这么做人……
我还要在此谢谢ZZXXQQ ，帮过我很多忙……
我在08上运行不了？
出来对话框后再拾取中心点（返回对话框时其中的坐标值还是0，没变化）点击确定后出现下面提示：
另外：标准齿、短齿、长齿是不是应该有默认标准齿？

运行不了呀，error: bad argument type: numberp: nil ZZXXQQ 发表于 2014-6-14 14:19 static/image/common/back.gif
Z版主，还是不行呀
试了几次，每次的结果都不一样 liuhaixin88 发表于 2014-6-14 14:55 static/image/common/back.gif
Z版主，还是不行呀
确实还存在问题…… ZZXXQQ版主解决了对话框中心点有值的问题，但还是画不出齿轮……
