What is a .ARX file?
The .ARX file extension stands for AutoCAD Runtime Extension File. This type of file is used with AutoCAD, which is a software application designed for drafting and designing in both 2D and 3D. The .ARX file contains parts of the application that have been developed using Autodesk's ObjectARX. ObjectARX is a programming environment provided by Autodesk that allows developers to write custom functions and extensions for AutoCAD. Developers use programming languages like C++, C#, and VB.NET to create these extensions.
To open a .ARX file, you will need to use Autodesk AutoCAD 2023 or the Autodesk ObjectARX software development kit (SDK). It's important to note that each version of AutoCAD has a corresponding version of the ObjectARX SDK. Therefore, you should ensure that the version of the SDK matches the version of AutoCAD you are using to avoid compatibility issues.
