Is this possible? I was trying to make a simple windows program that prompted the user to select a .dwg file and the program would list all the layers in a listbox. But the Database.ReadDWGFile procedure doesn't appear to work outside of AutoCAD (FileNotFound Exception). Can I have my windows program open AutoCAD in the background to achieve this?
Here's my code:
Imports Autodesk.AutoCAD.Runtime Imports Autodesk.AutoCAD.ApplicationServices Imports Autodesk.AutoCAD.DatabaseServices Imports Autodesk.AutoCAD.EditorInput Public Class Form1 Dim myLayers As ArrayList Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click Dim myDB As New Database(False, True) myDB.ReadDwgFile("C:\test.dwg", FileOpenMode.OpenForReadAndAllShare, True, "") Using myTrans As Transaction = myDB.TransactionManager.StartTransaction Dim myLayerTable As LayerTable = myDB.LayerTableId.GetObject(OpenMode.ForRead) Dim layerName As String = "" For Each myObjectID As ObjectId In myLayerTable Dim myLayer As LayerTableRecord = myObjectID.GetObject(OpenMode.ForRead) myLayers.Add(myLayer.Name) Next myTrans.Abort() End Using myDB.Dispose() For Each layerxx In myLayers ListBox1.Items.Add(layerxx) Next End Sub End Class
Solved! Go to Solution.
You can use either AutoDesk RealDWG
or Teigha™.NET for .dwg files
To modify files without Autocad.
These are both pay options.
The only free options is to have Autocad Installed and use ActiveX.
