The DXF file format was first introduced in 1982 as part of Autodesk's AutoCAD software. DXF files were intended at the time to allow data interchange between AutoCAD and other CAD related applications. The format has evolved over the years with the most recent version coming in 2007.

DXF files can contain either text or binary content describing Blocks, Entities, Objects and other information using a "Tagging" system. The DXF format is still popular today and can be opened with most popular CAD applications.

The STL file format has its roots in the 1980's and is the native file format for 3D Systems stereolithography CAD software. The format defines a triangulated mesh with vertices and faces and is a popular format for sharing 3D printable model files.

There were several formats that attempted to extend the STL format namely SolidView and VisCAM whose formats included limited 15-bit color information for each mesh face which is often ignored by most modern 3D software. The STL format can be either Text or Binary, our tools will support both formats.
