The Ultimate Guide to Turn JT Files into SimReady USD Content

This guide is part of the RapidPipeline 3D Formats Knowledge Database.

JT (originally Jupiter Tessellation, now JT Open) is a 3D data format developed by Siemens Digital Industries Software for lightweight visualization, collaboration, and PLM (Product Lifecycle Management). JT files provide highly compressed representations of 3D CAD data, making them ideal for sharing design information across organizations without exposing proprietary CAD data. The format supports multiple levels of detail (LOD), assembly structures, metadata, and annotations. JT is an ISO standard (ISO 14306) and is widely used in automotive and aerospace industries for design review and collaboration. It is a file format mostly used for lightweight 3D visualization and collaboration.

USD (Universal Scene Description) is the primary format to generate SimReady data, enabling 3D assets to be used in simulation environments such as NVIDIA Omniverse, PhysX, and more. For this to work properly, USD assets must adhere to the USD standard, and ideally bring metadata that helps to inform downstream simulation use cases about various simulation-relevant properties of the 3D asset.

There are various ways to generate USD files, but especially when starting from non-simulation formats like JT, it is not easy to perform a good conversion. Additional required steps might include material assignment (in case realistic materials are desired) and related steps like UV generation, but also metadata transfer from the original file to the final SimReady USD asset.

With RapidPipeline, the process of generating NVIDIA SimReady USD content from JT files is easy:

1. Download RapidPipeline Twin Studio, or one of the RapidPipeline 3D tool plugins (free trial available). Alternatively, you can also use RapidPipeline directly in the browser.
2. Perform the conversion from JT to USD. Store or download the resulting USD file, it's ready to use!
3. If you'd like to scale up the process, simply get in touch to acquire a license for the RapidPipeline 3D Processor, running as powerful batch processing tool that turns your entire library of JT files (or other files) into SimReady USD content.
