Collaborate on structured 3D models in visionOS

Learn how to bring structured 3D models to life in visionOS. We’ll cover USDZ preparation, show you how to manipulate individual entities within hierarchical assemblies, and inspect the internal components within a model with a cross-sectional plane. Create stunning exploded-view animations for design review and collaboration experiences on Apple Vision Pro.
