Open Design Alliance (ODA) — a member-driven, nonprofit organization of over 1,000 software developers in 40 countries — develops the Teigha® software development platform for CAD and other technical graphics applications.

ODA members obtain the Teigha software development platform for an annual membership fee. Combined with the  ODA’s relationships with well-known third party component vendors, ODA members are able to quickly design, build, and deliver technical applications for their customers.

The Teigha software development platform is available on a large number of operating systems such as Microsoft® Windows®, Apple® Mac OS®, various Unix systems, and Linux. ODA members can use the  C++, .NET, and ActiveX interfaces to develop their own applications. Teigha is able to exchange data through .dwg, .dgn, .stl and .pdf files.
