Use the Microsoft .NET Framework

To fully access AutoCAD automation objects from Microsoft Visual Studio. .NET, create references to the following files:

• The AutoCAD 2008 type library, acax17enu.tlb, located at c:\program files\common files\autodesk shared.
• The AutoCAD/ObjectDBX Common 17.0 type library, axdb17enu.tlb, located at c:\program files\common files\autodesk shared.

These references will make available the following primary interop assemblies: Autodesk.AutoCAD.Interop.dll (for AutoCAD-specific types), and Autodesk.AutoCAD.Interop.Common.dll (for types shared by ObjectDBXTM host applications). The interop assemblies are located in the global assembly cache; they map automation objects to .NET counterparts.

After you reference the type libraries, you can declare AutoCAD-based variables in Microsoft Visual Studio .NET, as in the following examples:

Dim objAcad As Autodesk.AutoCAD.Interop.AcadApplication

Dim objLine As Autodesk.AutoCAD.Interop.Common.AcadLine

You can load a .NET application using the NETLOAD command in AutoCAD.

Additional information about using a .NET application with AutoCAD is available from the Developer Center section of the Autodesk website
