I'm writing a program to import a WMF into the AutoCad Drawing. I haven't been able to find any reference for the import command, so I can't figure out why it's not working. According to Visual Studio, the Import command needs these things to work. Import(String FileName, Object InsertionPoint, Double ScaleFactor) Simplified Code: Imports Autodesk.AutoCAD.Runtime Imports Autodesk.AutoCAD.ApplicationServices Imports Autodesk.AutoCAD.DatabaseServices Imports Autodesk.AutoCAD.Geometry Imports Autodesk.AutoCAD.EditorInput Imports Autodesk.AutoCAD.Interop Dim AcadApp As Autodesk.AutoCAD.Interop.AcadApplication AcadApp = CType(GetObject(, "AutoCAD.Application.18.2"), Autodesk.AutoCAD.Interop.AcadApplication) acadDoc = AcadApp.ActiveDocument acadDoc.Import("C:\Users\C\Documents\Drawing1.wmf", New Point3d(2, 2, 0), 2.0) When I comment out the last line of code, acadDoc.Import("C:\Users\C\Documents\Drawing1.wmf", New Point3d(2, 2, 0), 2.0) It runs fine. The error I'm getting is when I run it AutoCAD, ************** Exception Text ************** System.ArgumentException: Value does not fall within the expected range. at System.StubHelpers.ObjectMarshaler.ConvertToNative(Object objSrc, IntPtr pDstVariant) at Autodesk.AutoCAD.Interop.IAcadDocument.Import(String FileName, Object InsertionPoint, Double ScaleFactor) at TestSelectingFiltering.TestSelecting.MyCommands.FilterBlueCircleOnLayer0() at Autodesk.AutoCAD.Runtime.CommandClass.InvokeWorker(MethodInfo mi, Object commandObject, Boolean bLispFunction) at Autodesk.AutoCAD.Runtime.CommandClass.InvokeWorkerWithExceptionFilter(MethodInfo mi, Object commandObject, Boolean bLispFunction) at Autodesk.AutoCAD.Runtime.PerDocumentCommandClass.Invoke(MethodInfo mi, Boolean bLispFunction) at Autodesk.AutoCAD.Runtime.CommandClass.CommandThunk.Invoke() Any help would be greatly appreciated, Thanks!

okay, im trying to get a connection to 2006 and im having problems. i used keen(through the interface) example and its throwing a COM exception, BUT it is creating the instance of autocad. I dont think it is connected to it, but it creates it. NOW, when i downloaded the objectARX for 2006 there where no interop.dll's just the 3 "acdbmgd" variations... im just learing how to work with c#. Can some one throw me a little bone here here is my code. public MainForm() { InitializeComponent(); IMessageFilter oldFilter = default(IMessageFilter); CoRegisterMessageFilter(this, oldFilter); AcadApplication acApp = GetAcApp("AutoCAD.Application.16.2"); } public AcadApplication GetAcApp(string progID){ AcadApplication acApp = null; try { acApp = (AcadApplication)Marshal.GetActiveObject(progID); } catch { try { Type acType = Type.GetTypeFromProgID(progID); acApp = (AcadApplication)Activator.CreateInstance(acType,true); } catch { MessageBox.Show("Cannot create object of type \"" + progID + "\""); } } if (acApp != null) { // By the time this is reached AutoCAD is fully // functional and can be interacted with through code acApp.Visible = true; return acApp; } return null; }
