如何使用vb.net調(diào)用cad進(jìn)行繪圖

你去查查書吧，書上挺詳細(xì)的，在這說不好說，你先在項(xiàng)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("不能運(yùn)行AutoCAD,請檢查是否安裝了AutoCAD") Exit Sub End If End If AcadApp.Visible = True '界面可視

VS2010中用VB.NET編程添加CAD引用出錯！坐等啊！

應(yīng)用程序啟動了沒

dim acadApp As AcadApplication

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

acadApp.Visible = True

啟動了CAD才能添加文件，其中18對應(yīng)的是cad2010，版本不同不一樣。

VB.Net讀取AutoCAD圖紙

如果可以的話請把分給我

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，代碼的話大同小異，思路是一樣的

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

VB.NET 如何通過按鈕打開AUTOCAD的指定文件

Process.Start(“cad主程序的路徑”，“要打開文件的目錄”)

比如用記事本打開 c:\1.txt

Process.Start("C:\Windows\notepad.exe", "c:\1.txt")
