The Open Design Alliance (ODA) announces its DRX Software Development Kit (SDK) available at no cost for public download from The DRX SDK is a new development platform that allows end-users to create extensions for DWGdirect™-based applications.

In order to take advantage of this new functionality, end-users of DRX-compatible host products — available from ODA members — can download the DRX SDK from and use it to create their own custom DRX extension modules. The DRX SDK already operates with DRX-compatible applications currently available from ODA members.

The SDK utilizes an object-oriented C++ interface and provides a wide range of capabilities, allowing end-users to create custom entities and custom commands. For example, the ODA uses this technology internally to implement walls, roofs, stairs, and more within its ADTdirect architectural package. These custom entities can be rendered and manipulated within any DRX-compatible host application.

When asked about this latest product release, Neil Peterson, Chief Technical Officer of the ODA, stated, “The release of the DRX SDK is a major milestone for the ODA. CAD end-users frequently need to create new entity types to represent domain-specific data, and the DRX SDK provides the tools needed to accomplish this task. In addition, unlike similar packages offered by other companies, DRX extension modules are usable within every DRX-compatible host application available from ODA members."

ODA investment in the development of the new DRX SDK further promotes its long-standing commitment to the open exchange of CAD data, along with its continued commitment to delivering the best service and value to its members and the CAD community.
