Autodesk Developer Network

Development Interfaces

Customize AutoCAD® with the OEM CAD development platform. This platform supports the following programming environments.

ObjectARX for AutoCAD OEM

The ObjectARX® programming environment provides an object-oriented, C++ API for developers to use, customize, and extend the AutoCAD OEM development platform. ObjectARX provides the greatest level of performance, functionality, and integration through direct access to AutoCAD OEM software's internal objects, database structures, graphics system, command registration, and processing.

Visual LISP in AutoCAD OEM

For development and debugging, the Visual LISP® environment incorporates a LISP integrated development environment (IDE) into AutoCAD OEM.

Microsoft .NET Framework Programming Support

Customize AutoCAD with OEM technology, which now provides managed wrapper classes that enable you to use the Microsoft® .NET Framework and to write programs in other languages, such as Visual Basic® .NET and C#.

The ObjectARX managed wrapper classes now include sophisticated selection, jig, and prompt support, complete events coverage previously only available to C++ reactors, and an application object model to give you convenient and readily discoverable access to the properties of the application, document, editor, and window objects of AutoCAD. .NET applications can easily create dockable palettes and tool palettes and can extend tabbed dialogs. The geometry library now includes 2D curves, and support for external references has been added.

Microsoft Visual Basic in AutoCAD OEM

AutoCAD OEM now supports VBA 7.1 for both 32 and 64 bit versions. However, the Visual Basic for Applications (VBA) engine is no longer provided with your AutoCAD OEM installation media. Please contact your Autodesk ISV partner representative for more information.
