In a recent Connected in 3D podcast episode, Ashley Crowder sat down with Aaron Luk, Director of Product Management at NVIDIA Omniverse, to explore the fast-evolving world of OpenUSD, simulation-ready 3D workflows, and how this standard is reshaping everything from robotics to enterprise design reviews.
As companies invest in digital twins, AI training, and simulation environments, one message was clear:
USD is the future of interoperable, scalable 3D—and it’s the backbone of NVIDIA Omniverse.
But for most companies, getting from raw CAD to a usable, simulation-ready USD file is still a painful, manual process.
That’s exactly where VNTANA comes in.
Why OpenUSD Is the New Standard for 3D Collaboration
As Aaron Luk explained, Universal Scene Description (USD) was born at Pixar but has quickly become the industry standard for assembling complex 3D scenes from many sources. With NVIDIA’s support and the formation of the Alliance for OpenUSD, it’s evolving into the foundation for:
- AI-powered robotics training
- Virtual factory simulations
- Autonomous vehicle development
- Cross-department digital twin collaboration
Unlike traditional file formats, OpenUSD allows for modularity—meaning you can layer in physics, materials, lighting, and logic without reprocessing everything from scratch.
That modularity is essential for companies with massive engineering pipelines—and it’s what enables tools like Omniverse to function like a “GitHub for 3D,” as Aaron puts it.
The Bottleneck: CAD Isn’t Built for USD
Despite the promise of USD, one challenge remains:
Most 3D data still originates in CAD formats that aren’t compatible with simulation engines.
Whether you’re working in SOLIDWORKS, Creo, or Inventor, those files are:
- Too heavy for real-time applications
- Structured for manufacturing, not visualization
- Missing the materials, hierarchy, and logic needed for simulation
Converting them to USD manually often takes hours or days per model—slowing down innovation and collaboration.
How VNTANA Bridges the Gap: From CAD to Omniverse in Minutes
VNTANA’s Intelligent Optimization™ platform automates the entire pipeline—from CAD ingestion to simulation-ready USD output.
Here’s how it works:
- Upload native CAD files (STEP, SLDASM, etc.) to VNTANA
- Our system auto-optimizes the geometry and converts it to lightweight USD
- We preserve mesh hierarchy and metadata needed for simulation
- You can instantly export to Omniverse, AR/VR tools, or embed in a web viewer
This makes it incredibly easy to build Omniverse-native pipelines without re-authoring geometry or manually reassembling exploded views.
Case Study: Astec Industries
A great example of this in action is Astec Industries, a global manufacturer of heavy industrial equipment.
Astec needed a way to:
- Train technicians in AR using exploded views
- Showcase machines to buyers without shipping equipment
- Prepare simulation-ready assets for internal design reviews
Using VNTANA, Astec:
- Uploaded CAD models of 50+ complex machines
- Automatically generated optimized 3D views in USD
- Delivered interactive content to Omniverse and web-based 3D viewers
- Enabled exploded views on Meta Quest for technician training—without any manual cleanup
This streamlined their sales, service, and simulation workflows using a single source of truth.
Final Thoughts: OpenUSD is the Future—But Only If It’s Usable
As NVIDIA Omniverse continues to expand and OpenUSD gains momentum as the industry’s default 3D format, enterprises must solve the bottleneck between CAD and simulation.
Without automated optimization and a scalable 3D content pipeline, teams risk stalling out in pilot purgatory.
That’s why platforms like VNTANA are essential—not just for visualization, but for real, scalable 3D deployment across every department.
