Every object detail page includes a full 3D viewer. It renders the object on the same theme-aware stage as the capture and course viewers, with studio lighting so metals and other PBR materials reflect properly, and a ground grid for scale. The same viewer, with the same panels, appears in the approvals queue. Navigation: left-drag to orbit, right-drag to pan, scroll or pinch to zoom. Click a part to select it; click empty space to deselect.

Inspecting the part hierarchy

When a model has real structure (more than one mesh), a Parts panel appears in the top-right corner showing the model’s assembly tree: groups and parts, nested the way the CAD file was authored. Conversion noise is filtered out, and each part row shows its triangle count. Single-mesh models get no panel. This is the place to validate a STEP upload: a CAD assembly’s sub-components should survive conversion as named parts rather than a single blob, and the tree is where you check that.
  • Click a row to select the part. It’s outlined in the viewport, and a translucent ghost shows through occluding geometry, so a part behind a panel still reveals where it sits, the way CAD tools show selections through walls. Clicking a part in the viewport selects it in the tree too, expanding and scrolling to its row.
  • Selection details: the panel footer shows the selected part’s name, triangle count, and bounding box, measured in the model’s own units, before any display normalization. Useful for checking that a part is really the size the drawing says.
  • Hover a row for two actions: the eye hides or shows the part and everything under it, and the isolate icon shows only that part’s subtree, hiding the rest of the model. Show all in the header restores everything.

​
Edges

The Edges toggle in the Parts panel header draws the sharp-angle outlines that make same-colored CAD faces readable. Edges default on for objects uploaded as STEP files and off otherwise; flipping the toggle is saved as the object’s preference, so every visit, on the web and in the headset, opens the object the same way. Edges on parts that are tiny on screen are suppressed automatically and return as you zoom in, so a dense assembly doesn’t turn into line mush at a distance.

​
Viewing animations

When a model carries animations, an Animations panel appears in the top-left corner listing each animation with its duration. The first one plays automatically on load, looping, so you see motion without hunting; click a row to switch animations, and use the header button to pause and resume in place. Exporters often split one authored animation into a clip per animated target (bones, shape keys, individual meshes). The panel groups those back into a single row and plays them together, so a character animates with its skeleton and its face at once.
