调整AutoCAD VBA以在Excel中工作

Question

我编写了一个可以在AutoCAD VBA中运行的代码（有帮助），但是我想对它进行调整，以便我可以从Excel运行它并将其集成到更长的宏中。我试过用ThisDrawing替换ACAD.ActiveDocument，但这不起作用。这是我的完整AutoCAD VBA代码：

Public Sub Section()
    Dim SolidObject As Acad3DSolid
    Dim NewRegionObject As AcadRegion
    Dim PlaneOrigin As Variant
    Dim PlaneXaxisPoint As Variant
    Dim PlaneYaxisPoint As Variant
    Dim PickedPoint As Variant
    On Error Resume Next
    With ThisDrawing.Utility
        .GetEntity SolidObject, PickedPoint, vbCr & "Select solid to cut."
        If Err Then
            MsgBox "Selected solid must be a 3DSolid"
            Exit Sub
        End If
        PlaneOrigin = .GetPoint(PickedPoint, vbCr & "Select point to define origin.")
        PlaneXaxisPoint = .GetPoint(PickedPoint, vbCr & "Select point to define x-axis.")
        PlaneYaxisPoint = .GetPoint(PickedPoint, vbCr & "Select point to define y-axis.")
        Dim minPoint As Variant, maxPoint As Variant
        Set NewRegionObject = SolidObject.SectionSolid(PlaneOrigin, PlaneXaxisPoint, PlaneYaxisPoint)
        With NewRegionObject
            MsgBox "Area: " & .Area
            MsgBox "Perimeter: " & .Perimeter

            .GetBoundingBox minPoint, maxPoint
            MsgBox "Min Point coordinates: (" & minPoint(0) & "," & minPoint(1) & "," & minPoint(2) & ")"
            MsgBox "Max Point coordinates: (" & maxPoint(0) & "," & maxPoint(1) & "," & maxPoint(2) & ")"
        End With
    End With
End Sub

您可以使用此函数来查看是否有正在运行的AutoCad实例，如果有，请获取它：

Function Set_Acad(Acad As AcadApplication) As Boolean
    On Error Resume Next
    Set Acad = GetObject(, "AutoCAD.Application") 'Get a running instance of the class AutoCAD.Application
    On Error GoTo 0
    Set_Acad = Not Acad Is Nothing
End Function

在主代码中被利用如下：

Option Explicit

Public Sub Section()
    Dim SolidObject As Acad3DSolid
    Dim NewRegionObject As AcadRegion
    Dim PlaneOrigin As Variant
    Dim PlaneXaxisPoint As Variant
    Dim PlaneYaxisPoint As Variant
    Dim PickedPoint As Variant

    Dim Acad As AcadApplication '<--| declare a variable of type 'AcadApplication'

    If Not Set_Acad(Acad) Then Exit Sub '<--| exit if there's no Autocad running instance, otehrwise set 'Acad' variable to it

    With Acad.ActiveDocument.Utility '<--| now you can use Acad to reference 'Autocad' application and all its objects/methods/properties

        On Error Resume Next
       .GetEntity SolidObject, PickedPoint, vbCr & "Select solid to cut."
        If Err Then
            MsgBox "Selected solid must be a 3DSolid"
            Set Acad = Nothing
            Exit Sub
        End If
        On Error GoTo 0

        PlaneOrigin = .GetPoint(PickedPoint, vbCr & "Select point to define origin.")
        PlaneXaxisPoint = .GetPoint(PickedPoint, vbCr & "Select point to define x-axis.")
        PlaneYaxisPoint = .GetPoint(PickedPoint, vbCr & "Select point to define y-axis.")
        Dim minPoint As Variant, maxPoint As Variant
        Set NewRegionObject = SolidObject.SectionSolid(PlaneOrigin, PlaneXaxisPoint, PlaneYaxisPoint)
        With NewRegionObject
            MsgBox "Area: " & .area
            MsgBox "Perimeter: " & .Perimeter

            .GetBoundingBox minPoint, maxPoint
            MsgBox "Min Point coordinates: (" & minPoint(0) & "," & minPoint(1) & "," & minPoint(2) & ")"
            MsgBox "Max Point coordinates: (" & maxPoint(0) & "," & maxPoint(1) & "," & maxPoint(2) & ")"
        End With
    End With

    Set Acad = Nothing    
End Sub

在Excel中创建一行（必须打开） 但您必须进入工具 - >参考并添加[AutoCAD 20xx类型库]

    Sub testline()
    Dim app
    Dim lineObj As AcadLine
    Dim startPoint(0 To 2) As Double
    Dim endPoint(0 To 2) As Double

    On Error Resume Next
        Set app = GetObject(, "AutoCAD.Application")
    On Error GoTo 0

    If (app Is Nothing) Then Exit Sub

    startPoint(0) = 100
    startPoint(1) = 100
    startPoint(2) = 0
    endPoint(0) = 200
    endPoint(1) = 200
    endPoint(2) = 0

    Set lineObj = app.Documents(0).ModelSpace.AddLine(startPoint, endPoint)

End Sub
