Open Design Alliance (ODA) today announced the release of version 3.6 of Teigha®, its software development platform for engineering applications. It is also the first version that combines support for .dgn and .dwg files into a single SDK.

Version 3.6 Enhancements

Version 3.6 incorporates performance enhancements and a large number of bug fixes donated to ODA by its members, as well as improvements made by the ODA development team. The update includes the following enhancements:

- Multi-threaded support for .dwg file loading
- Beta multi-threaded rendering support

ODA Chief Technology Officer Neil Peterson added, “3.6 is the first release of Teigha that supports multi-threading, allowing Teigha-based applications to take advantage of multi-core processors. The new multi-threaded support has increased loading and rendering performance by a factor of 2 on average using a 4-core processor, with better results for larger drawings.

Teigha version 3.6 is available now at [www.opendesign.com](http://www.opendesign.com/) for download by ODA members.
