JT (Jupiter Tessellation)
JT (Jupiter Tessellation) is a lightweight 3D visualization format developed by UGS (now Siemens) that lets manufacturers share and view complex assemblies without requiring the full CAD authoring tool. JT preserves geometry as a tessellated approximation alongside optional precise B-rep, supports product manufacturing information (PMI), and is published as ISO 14306. It is the dominant exchange format for visualization-based review, supplier collaboration, and manufacturing planning at automotive and aerospace OEMs.
Why it matters
JT solves a structural cost problem at scale: full CAD seats are expensive, and assemblies with hundreds of thousands of parts cannot be opened by every reviewer who needs to see them. ISO standardization moved JT from a Siemens-specific advantage into a neutral lifecycle asset, and it remains the canonical format for visualization-based collaboration across the multi-CAD enterprises that Teamcenter serves.
