从模型空间获取所有属性块
嘿，伙计们，我有一个程序，允许用户跨多个文件更新所有布局中的属性，但现在我需要跨多个文档更新模型空间中的属性。我试图修改它，但无法使其工作。有人能帮我做一下相反的事情吗？
'Returns all the attributed inserted blocks in a drawings layouts
Private Function GetBlocks(ByVal theDoc As AcadDocument, _
ByRef BlockStore As Scripting.Dictionary)
'Set dictionary's comparison mode to work with text
BlockStore.CompareMode = TextCompare
Dim aEntity As AcadEntity 'Stores each entity in turn
Dim aLayout As AcadLayout 'Stores each layout in turn
Dim aBlkRef As AcadBlockReference 'Stores a block reference
For Each aLayout In theDoc.Layouts 'Loop thru all the layouts
'The below condition is for performance, it excludes ModelSpace
If Not (aLayout.ModelType) Then
For Each aEntity In aLayout.Block 'Loop thru all entities
'If the current entity is a block insertion
If TypeOf aEntity Is AcadBlockReference Then
Set aBlkRef = aEntity 'Cast the entity into a block ref
'If the block insertion has attributes
If aBlkRef.HasAttributes Then
'Use a procedure to add block to dictionary
'Need procedure for isolated error handling
AddBlock BlockStore, aBlkRef.Name, aBlkRef.GetAttributes
End If
End If
Next aEntity
End If
Next aLayout
End Function

Dim aModel As AcadModelSpace
模型空间是一个块，并且只有一个块，因此不存在循环，而是使用
Set aModel = ThisDrawing。ModelSpace
或Set aModel = theDoc。模型空间 Dan，
查看此.dvb文件，以获取和替换属性值的选择集示例。
我一直在玩这个，还是拿不出来。当我运行它时，我得到一个错误，下一个实体被突出显示。我真的需要它来工作，但不幸的是我没有很多时间来玩它。

我不确定您是如何存储属性的（也许数组可以工作？）。只有一个属性吗？
否则，您将需要一种匹配attribute.name然后更改attribute.text并遍历它们的方法。 arizona，
我相信它们被存储为一个数组。我发布了适用于布局的完整代码(这是我首先应该做的)。基本上，我有大约60个平面图，上面有详细的标注。细节在最初的第9页和第10页，但是现在我必须把这些计划都加上去。所以我需要打开所有的图纸，检查所有的9到66，所有的10到67。这有意义吗？

嗯，我在这里的处境很糟糕。我在大楼的一个角落做了一个实验，然后将这些积木镜像到另一个角落。当我这样做的时候，属性当然会反映出来。我使用了一个lisp语言，它将这两种语言互换，因此详细信息编号再次位于顶部，工作表位于底部。我没有注意到的是，它交换了值，但没有交换标记。现在我需要增加图纸，但在镜像块上，详图值与图纸标记关联。这些都有意义吗。基本上我完蛋了。 有没有办法交换属性标记？ 是的，在你有标签的时候，你可以得到它的插入点。
