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:
- Teigha for .dwg files is a development platform available using C++, .NET, and ActiveX that is used with .dwg, and .dxf files and other graphics files (old names: OpenDWG and DWGdirect).
- Teigha for .dgn files is a development platform available using C++ that is used with .dgn files and other graphics files (old name: DGNdirect).
- Teigha for Architecture is a development platform available using C++ that is used in conjunction with Teigha for .dwg files to additionally support custom architecture objects.

Famous quotes containing the words open, design and/or alliance:
“All of the valuable qualities ... like helping in the development of others—will not get you to the top at General Motors, were that path open to women.... The characteristics most highly developed in women and perhaps most essential to human beings are the very characteristics that are specifically dysfunctional for success in the world as it is.... They may, however, be the important ones for making the world different.”
—Jean Baker Miller (20th century)
“I begin with a design for a hearse.
For Christ’s sake not black—
nor white either—and not polished!
Let it be weathered—like a farm wagon—”
—William Carlos Williams (1883–1963)
“In short, no association or alliance can be happy or stable without me. People can’t long tolerate a ruler, nor can a master his servant, a maid her mistress, a teacher his pupil, a friend his friend nor a wife her husband, a landlord his tenant, a soldier his comrade nor a party-goer his companion, unless they sometimes have illusions about each other, make use of flattery, and have the sense to turn a blind eye and sweeten life for themselves with the honey of folly.”
—Desiderius Erasmus (c. 1466–1536)
