JT Open Toolkit 11.2

JT Open Toolkit is a development library for working with JT, the ISO-standard 3D visualization format used across CAD, PLM, and digital manufacturing workflows. It gives software teams the building blocks to read, write, visualize, and interrogate JT content—making it easier to integrate lightweight 3D into custom applications, viewers, and data pipelines.

Key capabilities:

• Read and write JT files, including assembly structure and product metadata
• Access tessellated and precise geometry, materials, and attributes
• Work with product manufacturing information (PMI) and annotations
• Handle levels of detail (LOD) and streaming for large models
• Cross-platform C/C++ APIs designed for performance and scalability
• Sample code and utilities to accelerate integration and validation

Typical use cases include embedding JT viewing and interrogation in enterprise apps, enabling downstream visualization for large assemblies, and building translation or inspection tools that rely on accurate 3D and PMI data.

JT Open Toolkit is developed by Siemens PLM. The most popular versions of this product among our users are: 8.0, 8.5, 10.3, 10.8 and 11.2.
