The Open Design Alliance
Since the foundation in 1998 the Open Design Alliance and its members have fostered long-term relationships. Today there are 1,200 members in over 50 countries and 50% of these have been a member for more than five years. The ODA is governed by a board, which is nominated and elected each year by Supporting and Founding members. There are six membership levels: Supporting, Founding, Sustaining, Commercial, Associate and Educational. For more information on the ODA membership please go to Join the ODA.
Members of the ODA are committed to open industry-standard formats for the exchange of CAD data and to the maintenance of valuable data stored by legacy design systems. Building on their collective expertise and experience in data analysis, drafting, design, solid modeling and rendering, ODA members now develop and use engineering applications across all areas of business, science and education.
An annual membership fee gives members access to the Teigha software development platform. This provides them the tools to develop engineering applications ranging from custom data access and editing utilities, to visualization projects and full-scale CAD systems.
The Teigha platform supports the use of .dwg, .dgn, and .pdf files, and imports and exports many other file formats. It runs on Linux, Mac OS, Unix, and Windows. Members cooperate with the ODA development by submitting improvements for the common good, which leads to the development of higher-quality software.
