Open Design Alliance is a nonprofit organization creating software development kits (SDKs) for engineering applications. ODA offers interoperability tools for CAD, BIM, and Mechanical industries including .dwg, .dxf, .dgn, Autodesk Revit, Autodesk Navisworks, and .ifc files and additional tools for visualization, web development, 3D PDF publishing and modeling.

History

1998-2014

The Alliance was formed in February 1998 as the OpenDWG Alliance, with its initial release of code based on the AUTODIRECT libraries written by Matt Richards of MarComp.^{[citation needed]} In 2002, the OpenDWG library was renamed to DWGdirect,^{[citation needed]} and the same year, the alliance was renamed to Open Design Alliance.^[2]

On November 22, 2006, Autodesk 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.^{[citation needed]}

In 2008, support was added for .dgn files with DGNdirect.^{[citation needed]} 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.^{[citation needed]}

2015-2024

Since August 2017 (v. 4.3.1), Teigha contains production support for version 2018 .dwg files, including architectural, civil and mechanical custom objects.^{[citation needed]} In February 2018 (v. 4.3.2), support for STL and OBJ files was announced.^[3]

In September 2018 Teigha brand was removed.^[4]

In October 2018 ODA started work on IFC Solutio.^[5]

In January 2019 Drawings 2019.2 introduced extrude and revolve 3d solid modeling operations as part of the standard SDK.^[6]^[7] Also that month, ODA announced the release of its new BimNv SDK.^[8]

In May 2020 ODA switched to monthly releases. In June 2020 ODA released its free Open IFC Viewer, and in July 2021 ODA started development for STEP Support. In October 2021 ODA released its IFC validation engine. In January 2022 ODA started Scan-to-BIM development. In September 2022 ODA started MCAD SDK development, and in October 2022 ODA released STEP SDK for production use.^{[citation needed]}

ODA products and supported file formats

CAD

Drawings SDK is a development toolkit that provides access to all data in .dwg and .dgn through an object-oriented API, allows creating and editing any type of .dwg or .dgn drawing file, and can be extended with custom .dwg objects. (Old names: Teigha Drawings, Teigha for .dwg files and Teigha for .dgn files; OpenDWG and DWGdirect; DGNdirect.)

Drawings SDK also provides exchange of the following file formats to and from .dwg and .dgn:

Format	Export	Import
.dgn	No	Yes (import .dgn to .dwg only)
.dwf	Yes	Yes
.pdf	Yes	No
.dae (Collada)	Yes	Yes
.svg	Yes	No
Raster Formats	Yes	No
.stl	Yes	No
.hsf	Yes	No
Three.js	Yes	No

Architecture SDK is a development toolkit for building .dwg-based architectural design applications. It offers interoperability with Autodesk Architecture files (old name: Teigha Architecture).
Civil SDK is a development toolkit for working with Autodesk Civil 3D files. The Civil API provides read/write access to data in civil custom objects (old name: Teigha Civil).
Map SDK is a development toolkit for working with Autodesk® Map 3D custom objects in any ODA-based application.

BIM

BimRv SDK is a development toolkit for reading, writing, and creating .rvt and .rfa files.
IFC SDK is a development toolkit featuring 100% compatibility^{[citation needed]} with the buildingSMART IFC standard. It offers a geometry building module for creating IFC geometry, which includes the ODA facet modeler and B-Rep modeler.
BimNv is a development toolkit for reading, visualizing and creating Autodesk Navisworks files.
Scan-To-BIM is a development toolkit for converting point cloud data to 3D BIM models.

Mechanical

Mechanical SDK is a development toolkit for working with Autodesk Mechanical files.
STEP SDK is one of the newest ODA development toolkits; it provides access to STEP model data. In production since October 2022.
MCAD SDK is an open exchange platform for 3D MCAD file formats such as Inventor, IGES, Rhino, CATIA V4, CADDS, 3Shape DCM, CATIA V5, PLMXML, Parasolid, SolidWorks, Creo, STEP, SolidEdge, ProE, UG NX, CGR, CATIA V6, JT, and Procera.

ODA Core Platform Technologies

Visualize SDK is a graphics toolkit designed for engineering applications development.
Web SDK uses Visualize SDK to embed engineering models into web pages and create web/SaaS applications.
Publish SDK is a development toolkit for creating 2D and 3D .pdf and .prc models. All PDFs are compatible with ISO standards and Adobe tools. Publish SDK can create PRC-based 3D PDF documents that contain full B-Rep models and can include animation, interactive views, part lists, etc.

Asking those who benefit from ODA solutions to help support our Ukrainian developers: https://www.opendesign.com/blog/2022/april/oda-organizes-support-ukraine-developers

Apr 6, 2022^[13]

Since 2016 ODA has a 30-person development team in Chernihiv, Ukraine (almost students of Chernihiv Polytechnic National University).^[14]^[15]

Ukrainian engineers play an important role in developing ODA technologies, including our interoperability toolkits for DWG and Autodesk® Revit® files, and many other areas.
— Neil Peterson, ODA President, https://www.opendesign.com/blog/2022/april/oda-organizes-support-ukraine-developers

On 4 April, 2022 in a response to full-scale Russian invasion of Ukraine and continuous shelling of Chernihiv Neil Peterson, ODA President, announced^[14] a campaign^[16] for collecting money to donate Ukrainian team members and their families, and stated that help with relocation and temporary housing being provided.^[15]
