Information about STP and OBJ file formats

Full name Standard for the Exchange of Product model data OBJ geometry format
File extension .stp .obj
MIME type text/plain
Developed by ISO Wavefront Technologies
Type of format
Description STP is a neutral file format that allows the transfer of files between different CAD softwares. The development of STP started in 1984 as a successor of IGES, SET and VDA-FS. STP format (Standard for the Exchange of Product Data), is an ISO standard exchange format It is used for representing three-dimensional data in a format that can be recognized by multiple programs. ISO standard number: 10303. OBJ (or .obj) is a geometry definition file format first developed by Wavefront Technologies for its Advanced Visualizer animation package. The file format is open and has been adopted by other 3D graphics application vendors.
Technical details STP formats can be used to exchange data between CAD, Computer-aided manufacturing, Computer-aided engineering, Product Data Management/EDM and other CAx systems (Computer-aided technologies). STP is the same as STE and STEP. The disadvantage is that a STP file is not editable and the design tree of the model is not available either. The OBJ file format is a simple data-format that represents 3D geometry alone — namely, the position of each vertex, the UV position of each texture coordinate vertex, vertex normals, and the faces that make each polygon defined as a list of vertices, and texture vertices. Vertices are stored in a counter-clockwise order by default, making explicit declaration of face normals unnecessary. OBJ coordinates have no units, but OBJ files can contain scale information in a human readable comment line.
