Open Design Alliance

We are a technical consortium of 1,300 software developers involved in all areas of design. ODA members are committed to open industry-standard formats for the exchange of CAD data. Our technology platform, Teigha, provides developers with tools to create a rich variety of applications. Applications created with Teigha range from custom data access and editing utilities, to visualization projects and full-scale CAD systems. Our members cooperate by submitting improvements for the common good, resulting in higher-quality tools. Our platform supports the use of .dwg, .dgn, and .pdf files, and the import and export of many other file formats. It runs on Android, iOS, Linux, Mac OS, Unix, and Windows.
