--------------------------------------
先祝大家新年愉快！

第一次框选命令效果是删除短线，第二次框选命令效果是调整圆心位置等，如何只框选一次实现，求高手指点，谢谢！！

我有一个思路：根据第一次框选择，得到最大包围框（盒）boundingBox，做为第二次框选范围，不可以吗？不知道具体怎么写、、

lsjj · 发表于 2014-2-3 23:19:49

1. 選線後,依條件分二條路走就可以了
也可以
2. 程序中未被刪除的線形成一個選集
也可以
3. 變成二個副程序,在一個程序中分別調用

(defun c:nydd( / center circle i index l lineobj point point_01 point_02 radius sscircle ssline syh ...

好像不行，错误提示“命令: NYDD
选择对象: 指定对角点: 找到 5 个
选择对象:
; 错误: 参数太多”
我开始也这个写的，错在哪呢？？

广义来说就是：如何在主程序执行前过滤删除超短线
