PRC (Product Representation Compact) is a file format that can be used to embed 3D data in a PDF file.

This highly compressed format facilitates the storage of different representations of a 3D model. For example, it is possible to save only a visual representation that consists of polygons (a tessellation), and it is also possible to save the model's exact geometry (B-rep data). Varying levels of compression can be applied to the 3D CAD data when it is converted to the PRC format using Adobe Acrobat 3D.

The 3D data stored in PRC format in a PDF is interoperable with Computer-Aided Manufacturing (CAM) and Computer-Aided Engineering (CAE) applications.

History

The PRC file format was first presented by TTF (Trade and Technologies France) in 2003 at DMS in Tokyo.^[1] In 2006, the TTF company was acquired by Adobe Systems.^[2] In 2014, the PRC file format was approved as an international standard (ISO 14739-1:2014).^[3]
