PRC (file format)
PRC (Product Representation Compact; "précis" in French language) is a 3D 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, you can save only a visual representation that consists of polygons (a tessellation), or you can 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 the 3D PDF Converter plugin for Acrobat.
