The Open Design Alliance (ODA) has announced the production release of Teigha PRC, a 3D PDF component for Teigha. This component exports a .dwg or .dgn file to a PRC-based 3D PDF document.

The PRC file format is optimized to store, load and display 3D data such as geometry, assembly structures and product manufacturing information. PRC files encapsulated within ISO-standardized PDF, can be viewed universally which means that detailed 3D designs can be widely communicated, supporting a wide variety of workflows in architecture, engineering, design, manufacturing and elsewhere.
