As a result, STL files contain no scale information, and the units are arbitrary. All STL coordinates were required to be positive numbers in the original specification, but this restriction is no longer enforced, and negative coordinates are commonly encountered in STL files today. The file format is open and has been adopted by other 3D graphics application vendors.Īn STL file describes a raw, unstructured triangulated surface by the unit normal and vertices (ordered by the right-hand rule) of the triangles using a three-dimensional Cartesian coordinate system. obj) is a geometry definition file format first developed by Wavefront Technologies for its Advanced Visualizer animation package. Binary files are more common since they are more compact. The STL format specifies both ASCII and binary representations. STL files describe only the surface geometry of a three-dimensional object without representing color, texture, or other common CAD model attributes. It is widely used for rapid prototyping, 3D printing, and computer-aided manufacturing. Many other software packages support this file format. STL is a file format native to the stereolithography CAD software created by 3D Systems. stl Other file extensions associated with Online 3D Model Converter Common file extensions used by Online 3D Model Converter Although its likely, that some file extensions may be missing from the list of associated file extensions with the application, yet they can be opened, be part of, or otherwise be associated with the program. However most, if not all directly associated file extensions should be listed with its appropriate program. The list of extensions used or otherwise associated with the application may not be complete, because many common file extensions on our website, such as jpg (pictures) or txt (text files), can be opened by a large number of applications, or are too general file format.
