用VBA写一个让AUTOCAD的所有标注样式里的文字标注在尺寸线上

在VBA (Visual Basic for Applications) 中，编写一个脚本来改变AutoCAD中所有标注样式里文字标注的位置使其位于尺寸线上，需要对AutoCAD的对象模型有深入理解。以下是一个简化的示例，假设你想要将所有“默认”样式（例如，“DIMALIGNED”或你的自定义标注样式名称）的文字标注移到尺寸线中心：

Sub MoveAnnotationToDimensionLine()
    Dim acadApp As Autodesk.Autodesk.AutoCAD.ApplicationServices.Application
    Dim doc As Document
    Dim txtBlockRef As BlockReference
    Dim annot As Annotation
    Dim dimension As Dimension
    Dim i As Long

    ' 创建Application对象并激活当前文档
    Set acadApp = GetObject("AutoCAD.Application")
    Set doc = acadApp.ActiveDocument
    
    ' 遍历所有标注样式
    For Each dimStyle In doc.DrawingStylesManager.DimensionStyles
        If dimStyle.Name = "DIMALIGNED" ' 或者替换为你想要修改的样式名
            ' 获取该样式的标注实例
            For Each annot In doc.Annotations
                If annot.DatumReference.StyleName = dimStyle.Name Then
                    ' 查找关联的尺寸线
                    On Error Resume Next
                    Set dimension = annot.DatumReference.DimENSION
                    If Err.Number <> 0 Then
                        Debug.Print "无法找到尺寸线：" & annot.ObjectId
                        Err.Clear
                    Else
                        ' 如果找到尺寸线，移动标注到中心位置
                        txtBlockRef = annot.TextBlockReference
                        txtBlockRef.MoveTo(dimension.Centroid.X, dimension.Centroid.Y)
                    End If
                End If
            Next annot
        End If
    Next dimStyle

   acadApp.ExecuteCommand "regenall" ' 之后可能需要刷新视图
End Sub
