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.

STL Converter Capabilities

When converting 3D Model/Mesh files using our [ey] converter we will attempt to convert color materials into a suitable format for use in the converted file.

The X 3D file format extension was introduced by Microsoft with the launch of Version 2 of their 3D graphics API Direct X back in 2002. The format has evolved over the years however in 2014 the X file format was deprecated in favour of newer more capable formats such as FBX.

The format is a simple text based file capable of storing 3D mesh information such as vertices, faces, normals and material information. In addition to basic 3D information the format can also store animations with the X file format primarily used in the development of games.

Information for converting from STL to X

Your STL file will be converted to a X file using our unified 3D model and mesh conversion tool. Our STL 3D tool performs accurate conversions of 3D elements such as vertices, faces, normals and relevant material information. As STL supports color materials and X does not, our tool will not attempt to transfer any color information, your final 3D model will contain geometry data only.
