A JT file is a lightweight 3D model format used for storing and sharing product design data. It was introduced by Siemens PLM Software to facilitate fast and efficient visualization, collaboration, and CAD data exchange. The abbreviation "JT" is commonly believed to stand for "Jupiter Tessellation," referring to the technology used to compress 3D data.

JT files can store a variety of information, including:

  • Approximate (faceted) 3D models
  • Exact boundary representation surfaces (NURBS)
  • Product and Manufacturing Information (PMI)
  • Metadata

This format is widely used in industries like automotive and aerospace but is also compatible with other manufacturing applications. JT files are designed to be compact and easy to share while maintaining detailed design data.
