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)

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")

如何用.NET将DWG文件打印为PDF

执行步骤：打开一个dwg文件，用netload加载下面代码所在的.dll文件，再输入命令plottest，就得到输出结果（一个.pdf文件）。

要用到的参考：

AcDbMgd.dll;AcMgd.dll;AutoCAD 2010 Type Library;System.Windows.Forms; AutoCAD/ObjectDBX Common 18.0 Type Library.

VB.NET:

Imports System

Imports Autodesk.AutoCAD.Runtime

Imports Autodesk.AutoCAD.Interop

Imports Autodesk.AutoCAD.Interop.Common

Imports Autodesk.AutoCAD.ApplicationServices

Imports Autodesk.AutoCAD.DatabaseServices

Imports Autodesk.AutoCAD.EditorInput

Autodesk.AutoCAD.Runtime.CommandMethod("Plottest") _

Public Sub PlotToPDF()

Dim activeDoc As Document = Application.DocumentManager.MdiActiveDocument

Dim ThisDrawing As AcadDocument = CType(activeDoc.AcadDocument, AcadDocument)

Dim layout As AcadLayout = ThisDrawing.ActiveLayout

Dim MediaName As String = layout.CanonicalMediaName

If MediaName.Equals("") Then

activeDoc.Editor.WriteMessage("There is no media set for the active layout.")

Return

Else

activeDoc.Editor.WriteMessage(("The media for the active layout is: " + MediaName))

End If

Try

Dim oplot As AcadPlotConfiguration = ThisDrawing.PlotConfigurations.Add("PDF", layout.ModelType)

oplot.PaperUnits = AcPlotPaperUnits.acMillimeters

oplot.StyleSheet = "monochrome.ctb"

oplot.PlotWithPlotStyles = True

oplot.ConfigName = "DWG To PDF.pc3"

oplot.UseStandardScale = True

oplot.StandardScale = AcPlotScale.acScaleToFit

oplot.PlotType = AcPlotType.acExtents

oplot.CenterPlot = True

Dim oMediaNames As Object = layout.GetCanonicalMediaNames

Dim mediaNames As ArrayList = New ArrayList(CType(oMediaNames, String()))

For Each sName As String In mediaNames

If sName.Contains(MediaName) Then

oplot.CanonicalMediaName = sName

layout.CopyFrom(oplot)

layout.PlotRotation = AcPlotRotation.ac0degrees

layout.RefreshPlotDeviceInfo()

ThisDrawing.SetVariable("BACKGROUNDPLOT", 0)

ThisDrawing.Plot.QuietErrorMode = True

ThisDrawing.Plot.PlotToFile("c:/temp/d1.pdf", "DWG To PDF.pc3")

oplot.Delete()

oplot = Nothing

Return

End If

Catch es As System.Exception

System.Windows.Forms.MessageBox.Show(es.ToString)

End Try

End Sub

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 ""

End Select
