Gantry

Gantry is a tool for viewing, inspecting, editing, and converting 3D models. It supports USD, USDZ, and a wide range of other 3D formats, with real-time RealityKit preview and material editing.

Getting Started

To open a 3D model, choose File → Open (⌘O), click the Import button in the toolbar, or drag and drop a file onto the Gantry window. To open a second model in a new window, use File → New Window (⌘N).

The window is divided into three areas:

• Viewport (center): Interactive 3D preview rendered by RealityKit
• Inspector (right): Material editing, stage properties, and animation controls
• Toolbar: Import, export, environment picker, and inspector toggle

Quick Tips

Drag and Drop

Drag 3D files directly from Finder into Gantry to open them instantly. Supported format types are shown in the welcome screen.

Inspector

Press ⌘I to show or hide the inspector panel. The inspector gives access to material editing, stage metadata, and animation controls.

Undo

Gantry uses a layer-based undo system. Press ⌘Z to remove the last edit layer and step back through your changes.
