Open Design Alliance
Encyclopedia
The Open Design Alliance is a nonprofit organization of over 1,200 members in 50 countries which develops Teigha©, a software development platform used to create engineering applications including CAD. The main idea is to make core graphics technology accessible to software developers allowing them to focus on application development.
The ODA is developing Teigha for two main file formats:

History
- The Alliance was formed in February 1998 as the OpenDWG Alliance.
- In 2002, the OpenDWG library was renamed to DWGdirect.
- In October 2003 the alliance was renamed to Open Design Alliance.

sued the Open Design Alliance alleging that its DWGdirect libraries infringed Autodesk's trademark for the word "Autodesk", by writing the TrustedDWG code (including the word "AutoCAD") into DWG files it created. In April 2007, the suit was dropped, with Autodesk modifying the warning message in AutoCAD 2008 (to make it more benign), and the Open Design Alliance removing support for the TrustedDWG code from its DWGdirect libraries. - In 2008, support was added for .dgn files with DGNdirect.
- In April 2010, DWGdirect was renamed to Teigha for .dwg files, OpenDWG was renamed to Teigha Classic and DGNdirect was renamed to Teigha for .dgn files.
