The Ultimate Guide to Turn PRC/U3D Files into SimReady USD Content

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

PRC (Product Representation Compact) and U3D (Universal 3D) are compressed 3D file formats designed for embedding 3D content in documents, particularly PDF files. U3D was developed by the 3D Industry Forum and later standardized by Ecma International, while PRC was developed by Adobe as a more advanced successor. Both formats support geometry compression, materials, textures, and animations, making them ideal for technical documentation, 3D PDFs, and digital publishing. PRC offers better compression and more advanced features than U3D, supporting CAD data more effectively. It is a file format mostly used for 3D data embedding in documents and technical publishing.

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 PRC/U3D, 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 PRC/U3D 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 PRC/U3D 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 PRC/U3D files (or other files) into SimReady USD content.
