Add fast, reliable DWG file access to your application, and get to market faster with the world’s #1 DWG access SDK, RealDWG.
If you’re building a CAD application, supporting DWG is essential. As one of the most common design formats, DWG is used extensively across AutoCAD, Revit, Inventor, and thousands of third-party applications.
RealDWG is the world’s #1 DWG file access SDK, trusted for its perfect accuracy and full support of the proprietary DWG format. It provides complete access to 2D and 3D design data, including geometry, structure, text, and metadata -- so your users can view, edit, and share their designs with confidence.
With RealDWG, you can create a fully standalone application that supports DWG/DXF without any dependency on AutoCAD or other verticals, helping you get to market faster and stay fully in control of your product.

Case Studies
Frequently Asked Questions
There isn’t a trial version of RealDWG.
To test and evaluate RealDWG, please follow these steps:
Download and read about system requirements for the ObjectARX SDK here. These libraries are the API for AutoCAD (So you can see how well integrated RealDWG is!)
If you don’t have AutoCAD, you can download a 30-day trial version here.
If you’re not familiar with ObjectARX programming, you can get started here. Also, have a look at the sample projects that come with the SDK.
RealDWG uses the ObjectDBX part of the Object ARX libraries. (Please be aware that any UI or draw functions are NOT included in RealDWG. However, all file reading, file writing, and geometry functions are.)
Using the ObjectARX SDK, it is possible to do a “proof-of-concept” to validate the intended behavior. As RealDWG is a subset of ObjectARX you need to make sure critical features are kept within the RealDWG parts of the API.
No, RealDWG is a Windows desktop application only, and it is not permissible to host a RealDWG application on a server. We would suggest that you consider HOOPS Visualize or APS for a server solution.
A RealDWG license can only be purchased for a maximum term of 12 months. The license commences on the effective date when the Autodesk contract is signed and expires one year later. It is licensed on an annual-renewal basis and is not perpetual.
No, RealDWG is read/write only. It does not provide drawing/display/viewing/plotting capabilities.
Access to technical support for RealDWG is available through the Autodesk Developer Network (ADN).
No, RealDWG is a subset of ObjectARX that contains only the APIs for reading and writing DWG and DXF file formats. Unlike ObjectARX, RealDWG does not require a dependency on AutoCAD
