Collada is an XML-based file format designed to exchange digital assets between interactive 3D graphics applications. The Collada interface for Teigha was developed in response to requests from ODA members for better compatibility between the .dwg file format and the numerous applications that support Collada. The new Collada interface makes it easy for ODA members to support Collada in their Teigha-based applications. For more information on Collada please refer to: http://www.khronos.org/collada/
The interface is available as a stand-alone conversion application for Windows, and full API and platform support will be available to ODA members in the upcoming 3.5.1 release of Teigha due out by the end of the year.
