块编辑器只能编辑内部块,应当尽量使用内部块0 X! k; P( l% }1 }
外部块的清理方法：可以用VBA编程解决，新建一个块，把外部块的引用指向这个新建块就可以把外部块变成内部块；
2 ^9 ^) U7 y" o2 t9 m \这时外部块是清理不掉的，保存图纸，然后关闭 重新打开就没有外部块了。, e+ H, o# W: i/ a
VBA代码如下：
: M. F2 {0 Z2 R) A' O5 U9 k/ pSub ReplaceBlockReference()' c; L- r# S6 K0 Z8 ~! n" M
On Error Resume Next
$ n/ b8 |/ b/ v' t2 @3 t! z" k / @0 K, E1 q4 ?% b1 W
Dim blockEnt As AcadBlockReference& V& V k2 m: E, U; _8 a! O6 D8 l
