Description
The STEP file format is a 3D format defined in 1994 and used to store 3D objects for use in computer-aided design (CAD) applications. STEP files are text-based, formatted files containing one command per line, with a full 3D model comprising of many commands.
Although STEP files are widely supported by most CAD applications, the format does have its limitations, such as the necessity to read the complete file into memory in order to parse the contents, and due to the textual storage of information, the files can be quite large and time-consuming to process.
STEP Notes
IDTF files, when imported, will be converted to 3D geometry comprising vertices and faces. If the IDTF file contains color information, this will be converted where possible.

Description
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.
IDTF Notes
Currently, only mesh geometry will be carried over from your source model to the final IDTF file for download.
