ObjectARX

The ObjectARX® programming environment provides object-oriented C++, C#, and VB .NET application programming interfaces for developers to use, customize, and extend AutoCAD® software and AutoCAD-based products like AutoCAD® Architecture, AutoCAD® Mechanical, and AutoCAD® Land Desktop software.

ObjectARX libraries provide a versatile set of tools for application developers to take advantage of the open architecture of AutoCAD software and provide direct access to the AutoCAD database structures, graphics system, and native command definition.

ObjectARX technology helps you develop fast, efficient, compact applications. It enables power users to customize AutoCAD software and frees CAD designers from repetitive tasks. Smaller files, faster drawing operations, and smooth interoperability make an application built with ObjectARX your best choice for a design software solution.
