Q1: 如何用vb.net编程在cad图形中插入dwg图块？

Dim ppr As PromptPointResult = ed.GetPoint("请选择插入点：")

Dim pt As Point3d = ppr.Value

utility.WriteToEditor(pt.ToString())

Dim pidBlock As New PIDBlock()

'自己定义的图块类，保存图块的路径和名称 

pidBlock.Name = "sample"

pidBlock.Path = blockPath  "b_sample.dwg"

Using blkDb As New Database(False, True)

'read drawing 

blkDb.ReadDwgFile(pidBlock.Path, System.IO.FileShare.Read, True, Nothing)

blkDb.CloseInput(True)

Using docLock As DocumentLock = doc.LockDocument()

'多文档要先这样，否则报至命错误 

Using t As Transaction = doc.TransactionManager.StartTransaction()

'insert it as a new block 

Dim idBTR As ObjectId = doc.Database.Insert(pidBlock.Name, blkDb, False)

'create a ref to the block 

Dim bt As BlockTable = DirectCast(t.GetObject(doc.Database.BlockTableId, OpenMode.ForRead), BlockTable)

Dim btr As BlockTableRecord = DirectCast(t.GetObject(bt(BlockTableRecord.ModelSpace), OpenMode.ForWrite), BlockTableRecord)

Using bref As New BlockReference(pt, idBTR)

btr.AppendEntity(bref)

t.AddNewlyCreatedDBObject(bref, True)

End Using

t.Commit()

End Using

End Using

Q2: VB.NET 如何通过按钮打开AUTOCAD的指定文件

Process.Start(“cad主程序的路径”，“要打开文件的目录”)

比如用记事本打开 c:\1.txt

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

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
