Get to market faster and give your products a competitive edge with the RealDWG® software development kit (SDK) from Autodesk. It's the only software development toolkit that provides DWG™ file read/write capability from the source.
The RealDWG toolkit helps you share design data with confidence using the native DWG file format so you can create applications with 100 percent DWG read/write capability. Deliver your products with the latest DWG file technology and DWG viewers available from Autodesk.
The RealDWG software library allows C++ and .NET developers to read and write DXF™ and DWG™ files created with AutoCAD® software. The most current version of RealDWG provides compatibility with AutoCAD DWG files, including read and write support for AutoCAD releases since AutoCAD Release 14 and drawing enhancements available with the most current version of AutoCAD. RealDWG is also used internally by Autodesk to provide DWG support in non-AutoCAD-based applications, such as Autodesk® Revit® software-based products and Autodesk® Inventor® software products.
The "My First AutoCAD plug-in" training is using the .NET API environment, which can also be used with RealDWG. It may be of interest if you are just getting started. Remember that RealDWG is the database component of AutoCAD and uses the same programming constructs.
What is the difference between RealDWG® and ObjectARX for AutoCAD? RealDWG is a subset of the ObjectARX® programming environment and contains the APIs for reading and writing AutoCAD DXF and DWG files. RealDWG does not contain support for viewing and accessing the AutoCAD user interface.
Also, ObjectARX applications always require AutoCAD as their host application. RealDWG does not require the presence of AutoCAD software. RealDWG is used to create host applications, but ObjectARX is not.
Is RealDWG® available for 32-bit and 64-bit operating systems? RealDWG® 2020 is only available for 64-bit operating systems. RealDWG® 2018 and 2019 are available for both 32-bit and 64-bit operating systems. Deployment of 32-bit applications on a 64-bit operating system is not supported. Developer support for RealDWG® is available through the Autodesk public forums(choose the ObjectARX or .NET forum depending on which RealDWG API you are using) or through the Autodesk Developer Network (ADN).
