块编辑器只能编辑内部块,应当尽量使用内部块
5 L' i& O0 W, c( Q$ h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；
' O/ d A/ k- m0 ^: _9 ^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。/ }/ Z$ _& Z& q% Q2 ?& `8 t
VBA代码如下：6 u" V" u* M5 R& Q! e+ J+ I
Sub ReplaceBlockReference()7 D2 O* A, m0 Y- V6 y* X
On Error Resume Next
9 z; V$ c4 c1 X. r5 I
