vba - 如何引用 AutoCAD block

Question

我有 autocad 项目，其中 1 个动态 block 是我试图从 excel 更改的。
这是我用来更改 block 的 vba 脚本:

Dim dybprop As Variant, i As Integer
Dim bobj As AcadEntity

For Each bobj In ACADApp.ModelSpace
    If bobj.ObjectName = "AcDbBlockReference" Then
        If bobj.IsDynamicBlock Then
            If bobj.EffectiveName = "AdjBlock" Then
                dybprop = bobj.GetDynamicBlockProperties
                For i = LBound(dybprop) To UBound(dybprop)
                    If dybprop(i).PropertyName = "Distance1" Then
                        dybprop(i).Value = 50.75
                        Acad.Application.Update
                    End If
                Next i
            End If
        End If
    End If
Next

End With

当我在 AutoCAD VBA 中运行它时，它运行良好。比我创建 Excel VBA 项目并复制此代码。在运行它之前，我创建了与现有 AutoCad 项目的连接，如下所示:

  On Error Resume Next

   Dim ACADApp As AcadApplication
   Dim a As Object

   Set a = GetObject(, "AutoCAD.Application")

   If a Is Nothing Then
      Set a = CreateObject("AutoCAD.Application")

      If a Is Nothing Then
         MsgBox "AutoCAD must be running before performing this action.", vbCritical
         Exit Sub
      End If
   End If

   Set ACADApp = a

   Set ACADApp.ActiveDocument = ACADApp.Documents.Open("c:\KIRILL\Programming\Drawing1_VBATest.dwg")

当我从 Excel VBA 运行它时 - 出现 AutoCAD 项目但没有任何变化。老实说，我不知道为什么在 Excel VBA 中它不起作用，而在 AutoCAD 中它起作用。可能有人以前遇到过这个问题吗？提前致谢。

附言完整的 Excel VBA 代码:

Sub Button9_Click()

  On Error Resume Next

   Dim ACADApp As AcadApplication
   Dim a As Object

   Set a = GetObject(, "AutoCAD.Application")

   If a Is Nothing Then
      Set a = CreateObject("AutoCAD.Application")

      If a Is Nothing Then
         MsgBox "AutoCAD must be running before performing this action.", vbCritical
         Exit Sub
      End If
   End If

   Set ACADApp = a

   Set ACADApp.ActiveDocument = ACADApp.Documents.Open("c:\KIRILL\Programming\Drawing1_VBATest.dwg")

Dim dybprop As Variant, i As Integer
Dim bobj As AcadEntity

For Each bobj In ACADApp.ModelSpace
    If bobj.ObjectName = "AcDbBlockReference" Then
        If bobj.IsDynamicBlock Then
            If bobj.EffectiveName = "AdjBlock" Then
                dybprop = bobj.GetDynamicBlockProperties
                For i = LBound(dybprop) To UBound(dybprop)
                    If dybprop(i).PropertyName = "Distance1" Then
                        dybprop(i).Value = 50.75
                        Acad.Application.Update
                    End If
                Next i
            End If
        End If
    End If
Next



End Sub

您是否尝试过添加引用库？

你可以去:
