块编辑器只能编辑内部块,应当尽量使用内部块7 g4 J P4 }( ~: Z, \6 I [
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；
4 ^: M, j4 G# l/ D8 f4 i+ E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。: f" X: r1 I7 ^
VBA代码如下：
: b( X- s, k- q; nSub ReplaceBlockReference()5 F, _( b* A0 m, B- P$ _; W
On Error Resume Next0 q7 g8 q5 u7 F3 Y$ }( t/ t
8 m# W6 E( \0 G9 P: y6 Q; u# j Dim blockEnt As AcadBlockReference
% h z( K2 s" y9 w2 t. E Dim blkName As String
* t1 a7 S. z6 _( h: |- H! m8 d% [9 }7 W Dim getobj As Object
- F. ~; G2 n$ W9 |2 w2 r2 r Dim p As Variant% n0 d7 u* B' }) w1 A
Dim I As Integer
I; L: P: P* X- l4 x) K + ?# c+ z2 v6 j0 E9 K4 L7 [
blkName = ThisDrawing.Utility.GetString(0, vbCrLf & "替换为:")
* J4 m, ` f W) g4 X8 ~ If blkName = "" Then
. {2 L( |$ c: S ThisDrawing.Utility.GetEntity getobj, p, "选择要替换后的图块 即新块"
( P% O# `$ f( Z4 i% P9 i blkName = getobj.Name
: z8 A. U6 V& y5 `9 K( y- U Else( ]: O$ i# r1 m; W- d! n
End If
; n5 _% D" V1 J& y% o5 W'加入选择集
