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 IDTF file format is a bespoke format that enables interactive 3D content to be embedded within a PDF document. Currently only Adobe Reader and PDF-XChange Editor are able to render PDF documents that contain this 3D content.

IDTF files are a simple text-based format containing 3D geometry defined using vertices and faces in a structured hierarchy. Prior to importing the IDTF file to the PDF it must be converted to a U3D file format using one of the free applications such as IDTFConverter.

Information for converting from STL to IDTF

Your STL file will be converted to a IDTF 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 IDTF does not, our tool will not attempt to transfer any color information, your final 3D model will contain geometry data only.
