#### Create simple BIM entities programmatically

**Scottsdale, AZ: August 28, 2017** – Open Design Alliance (ODA) today announced the release of version 4.3.1 of Teigha BIM, its SDK for Autodesk® Revit® files. Version 4.3.1 introduces support for version 2018 .rvt and .rfa files, and contains a number of additional enhancements.

“The ability to write arbitrary geometry to a Revit file is an important milestone in our ongoing efforts to provide full support for entity creation,” commented Neil Peterson, ODA President. “With Teigha BIM 4.3.1, client applications can export 3d solid geometry as well as 2d geometry to a Revit file. By Q4 this year, clients will be able to create an initial set of parametric entities.”

Sergey Vishnevetsky, ODA Development Director, said, “Teigha BIM 4.3.1 also adds support for visual styles and fill patterns for rendering, and Collada import. In addition to freeform and direct shape elements, creation support is available for curves, sketch planes, custom parameters, views and connectors.”

Teigha BIM 4.3.1 is available for download by subscribers at [www.opendesign.com](/members/memberfiles).
