VB.NET连接AutoCAD出错

这个是vb.net教材里面的吧，我也是前两天刚下的。遇到类似的问题，下面是我的解决办法

首先要参考引用Autodesk.AutoCAD.Interop.dll还有Autodesk.AutoCAD.Interop.Common.dll

然后代码有两处也需要相应修改，我用的是.NET 的 vb2008

'Dim AcadApp As AutoCAD.AcadApplication

Dim AcadApp As Autodesk.AutoCAD.Interop.AcadApplication

Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click

Call 连接AutoCAD()

End Sub

Sub 连接AutoCAD()

On Error Resume Next

AcadApp = GetObject(, "AutoCAD.Application")

If Err.Number Then

Err.Clear()

AcadApp = CreateObject("AutoCAD.Application")

If Err.Number Then

MsgBox("不能运行AutoCAD,请检查是否安装了AutoCAD")

Exit Sub

End If

End If

AcadApp.Visible = True '界面可视

'AcadApp.WindowState = AutoCAD.AcWindowState.acMax '界面最大化

AcadApp.WindowState = Autodesk.AutoCAD.Interop.Common.AcWindowState.acMax

AppActivate(AcadApp.Caption) '显示AutoCAD界面

End Sub

Q1: vb.net打开cad画图的问题？

你去查查书吧，书上挺详细的，在这说不好说，你先在项目里引用。然后 Dim acadapp As AcadApplication Dim acaddoc As AcadDocument On Error Resume Next AcadApp = GetObject(, "AutoCAD.Application") If Err.Number Then Err.Clear() AcadApp = CreateObject("AutoCAD.Application") If Err.Number Then MsgBox("不能运行AutoCAD,请检查是否安装了AutoCAD") Exit Sub End If End If AcadApp.Visible = True '界面可视

Q2: VS2010中用VB.NET编程添加CAD引用出错！坐等啊！

应用程序启动了没

dim acadApp As AcadApplication

acadApp = CType(CreateObject("AutoCAD.Application.18"), AcadApplication)

acadApp.Visible = True

启动了CAD才能添加文件，其中18对应的是cad2010，版本不同不一样。

Q3: VB.Net读取AutoCAD图纸

如果可以的话请把分给我

以下是cad2007版的，引用autocad 2007 type library 和autocad/objectdbx common 17如果是04或者版本更低的只要引用autocad 2007 type library，代码的话大同小异，思路是一样的

 

Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load

        On Error Resume Next

        Dim acadapp As Autodesk.AutoCAD.Interop.AcadApplication

acadapp = GetObject(vbNullString, "autoCAD.application")

        Dim acaddoc As Autodesk.AutoCAD.Interop.AcadDocument

        acaddoc = acadapp.ActiveDocument

        Dim Ms As Autodesk.AutoCAD.Interop.Common.AcadModelSpace

        Ms = acaddoc.ModelSpace

        Dim acadObjectI As Autodesk.AutoCAD.Interop.Common.AcadObject

        Dim Linei As Autodesk.AutoCAD.Interop.Common.AcadLine

        Dim Circlei As Autodesk.AutoCAD.Interop.Common.AcadCircle

        Dim Polylinei As Autodesk.AutoCAD.Interop.Common.AcadPolyline

        Dim pt As Autodesk.AutoCAD.Interop.Common.AcadPoint

For Each acadObjectI In Ms

            Debug.Print(acadObjectI.ObjectName)

            Select Case acadObjectI.ObjectName

                Case "AcDbLine"

                    Linei = acadObjectI

                    Debug.Print("X =" Linei.StartPoint(0).ToString)

                    Debug.Print("Y =" Linei.StartPoint(1).ToString)

                Case ""

                Case ""

End Select

Next

    End Sub

你去查查书吧，书上挺详细的，在这说不好说，你先在项目里引用。然后 Dim acadapp As AcadApplication Dim acaddoc As AcadDocument On Error Resume Next AcadApp = GetObject(, "AutoCAD.Application") If Err.Number Then Err.Clear() AcadApp = CreateObject("AutoCAD.Application") If Err.Number Then MsgBox("不能运行AutoCAD,请检查是否安装了AutoCAD") Exit Sub End If End If AcadApp.Visible = True '界面可视
