求助 新的问题 还是齿轮参数化

wanxlxg

下面是我的程序,现在有个问题就是,我在运行程序的时候 如果把齿数 z 的值改为 小于15的数的话 齿轮导角就不能生成,错误提示说 A fillet cannot be created with the given radius between the two given entities.
我理解是 最后的画导角命令中 的nearpoint 的问题但是怎么修改确不知道了,那位大侠 帮我出出主意吧

(红色部分是错误行)

另外问个小问题,我想把 导角半径 定义在 0和1之间 应该怎么写程序呢?

还是使用插入代码功能上代码吧，不然别人复制了也没法用。

.....插入代码不会用啊！别笑话我啊呵呵，要不我把py文件法给你 ？给我你的联系方式把 qq ，msn都可以！谢谢嘿嘿

上面是试发 没弄明白。。。。大家别介意啊

JingheSu

你可以把py文件弄成一个压缩包然后作为附件传上来的。

我传上来了,斑竹大人帮忙给点建议,最近出门了,没及时上论坛嘿嘿

自顶下呵呵
