The Ultimate Guide to Turn JT Files into Omniverse SimReady USD Content

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.

Omniverse supports various file formats. However, the native file format is USD, which is the officially recommended file format for best performance.

USD (Universal Scene Description) is the primary format for Omniverse SimReady data, it enables 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 Omniverse SimReady USD asset.

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

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