多选删除扩展数据

panliang9 · 发表于 2015-1-26 11:02:00

带扩展数据的图元一旦放进块中，很多时候会出现“参照丢失，无法编辑”的情况，很是恼火！

找了一个删除扩展数据的程序，能用，但是只能一个一个对象的选择，不能框选，多选，下面是我找到的程序，

尊敬的版主大人，还有路过的各位高手，能不能帮我改一下，使它能够框选多选直接删除呢！

(defun c:DelXdata()
(setq l (car (entsel "Pick object:")))
(if l (progn
(redraw l 3)
(setq le (entget l '("*")) )
(setq xdata (assoc '-3 le))
(setq le
(subst (cons (car xdata) (list (list (car (car (cdr xdata)))))) xdata le))
(entmod le)
(redraw l 4)
le
)
)
)

附件内是我需要删除扩展数元数据的样例图形！

大家帮帮我！

这是一个国外的贴子，贴子中提到使用宏来删除，也给出了代码，但我没能成功加载，

惭愧！

这个代码里的daa不就是删除图里所有对象的扩展数据的吗？想框选的就把ssget后的X去掉就可以了啊。

panliang9 · 发表于 2015-1-26 15:59:03

谢谢 “flytoday”！

太感谢了！这就是我需要的！

我前面也搜了一下版里，没想到G版已经写出我需要的东西了！

非常开心！

也谢谢 “springwillow”！

谢谢你的指点！我真是什么都不懂呢！
