OBJ Export for Acrobat is a Wavefront OBJ file export plug-in for Acrobat®. This plug-in gives Acrobat the ability to export objects from 3D PDF file in Acrobat to 3D polygon mesh objects in a Wavefront OBJ file. OBJ Export for Acrobat tessellates objects in a 3D PDF into a set of triangular meshes. These meshes are then exported to an OBJ file as mesh objects. The OBJ file can then be imported into a variety of CAD applications. OBJ Export for Acrobat is very easy to use. Once installed, it automatically loads itself into Acrobat and adds a new menu called "OBJExport" to the Acrobat menu.

The file format is open and has been adopted by other 3D graphics application vendors, making it a universally accepted geometry file format. The OBJ file format is a simple data format that represents 3D geometry alone - namely, the position of each vertex, the texture coordinate associated with a vertex, the normal at each vertex, and the faces that make each polygon.
