Information about SLDPRT and STL file formats

Full name SolidWorks Part File Stereolithography File Format
File extension .sldprt .stl
MIME type
Developed by Dassault Systèmes 3D Systems
Type of format
Description SolidWorks CAD program 3D image format file with a three-dimensional object or part that can be combined with other parts into a single assembly (SLDASM) file. Adobe Acrobat 3D or Acrobat Pro 9 and newer can be used to open SLDPRT files. STL is a file format native to the stereolithography CAD software created by 3D Systems. This file format is supported by many other software packages. It is widely used for rapid prototyping, 3D printing and computer-aided manufacturing. STL files describe only the surface geometry of a three-dimensional object without any representation of color, texture or other common CAD model attributes. The STL format specifies both ASCII and binary representations. Binary files are more common, since they are more compact.
Technical details An 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. In the original specification, all STL coordinates were required to be positive numbers, but this restriction is no longer enforced and negative coordinates are commonly encountered in STL files today. STL files contain no scale information, and the units are arbitrary.
