lisp可以尝试调用acad命令：-attedit来编辑属性；. o; g8 c" ]5 W: B4 ]
可以试试下面的代码：

VBA完成属性编辑相对来说操作更方便，VBA可以按下面的代码获得和编辑属性+ E! x) K1 B; l- n9 F+ N4 O
' Get the attributes for the block reference
: [- |; y+ L4 `8 b. ~ Dim varAttributes As Variant, p, x# d+ M0 j* C; k$ ~% E% v5 ^
varAttributes = blockRefObj.GetAttributes
8 u) A0 a" i3 K% [ j
) \1 b' [1 o/ N7 i, }! b ' Move the attribute tags and values into a string to be displayed in a Msgbox
( t4 ^: s8 Z- v- w) V6 b Dim strAttributes As String; V. t! J7 z* k
Dim I As Integer8 `7 t c1 j# P8 E
For I = LBound(varAttributes) To UBound(varAttributes)
- U2 Y# P3 r! U0 `! M7 N, w strAttributes = strAttributes & " Tag: " & varAttributes(I).TagString & _
D5 Y4 @! @& l% O7 I " Value: " & varAttributes(I).textString & " " A. K- p8 k0 x2 p. ]* y" B
Next
) S* H3 w* t" L0 ~! o- n MsgBox "The attributes for blockReference " & blockRefObj.name & " are: " & strAttributes, , "GetAttributes Example"
# g4 }6 r5 v$ t0 s( f" f / t0 C4 i6 N# G& W: |
' Change the value of the attribute
% {1 Z- l7 W! J) t ' Note: There is no SetAttributes. Once you have the variant array, you have the objects.
