What is a .JT file?
JT is a lightweight 3D format for sharing and reviewing CAD models. Created by Siemens.
- Did you know
- JT became an ISO standard in 2012 for exchanging 3D product data across the industry.
- JT stands for Jupiter Tessellation, and the format was originally designed by Engineering Animation and Hewlett-Packard as the Direct Model toolkit.
- JT passed through UGS, which named it their master 3D format, before Siemens acquired UGS and made JT its interoperability standard.
- What Analyser reads
- Header and metadata extraction for 3D meshes, voxels, BIM, point clouds and Gaussian splats: Wavefront OBJ, Stanford PLY, OFF, glTF, AMF, MagicaVoxel VOX, COLLADA DAE/ZAE, USD crate, X3D/VRML, LightWave LWO/LWS, Quake MD2/MD3/MDL, VRM avatars, Siemens JT, LAS/LAZ/PCD/PTS/E57 LiDAR clouds, IFC BIM, and .splat/.spz - vertex/face/point counts, bounding boxes, units and authoring tool.
- Depth of analysis
- .JT is an identification-grade format: Analyser recognises it from its bytes and decodes the header metadata it carries, rather than opening it in a full viewer. Formats that do get a full viewer are marked "Full" on the formats page.
- Open a .JT file
- Drag a .JT file onto the Analyser home page (or tap to pick one). It is identified entirely in your browser - nothing is uploaded, there is no account, and it works offline once installed.
