Objects and Hierarchy

​

Adding Objects

Objects can be added in several ways:

• Ribbon 3D Objects
• Viewport context menu Add Object
• Hierarchy context menu Add Object
• Dragging a valid GLB file onto the viewport

Depending on where the action starts, the new object can be placed:

• On the scene floor
• At a right-clicked location
• As a child of the selected object

​

Creating Empty Objects

From the hierarchy context menu, users can create an empty object. This is useful for grouping or parent structure.

​

Object Library

The object library is a dialog used to insert models from the asset library. Object library dialog for searching and selecting 3D assets.

​

Available Features

• Search field: Search 3D objects...
• Tag filter button
• Tag count badge when filters are active
• Clear action for selected tags
• Thumbnail grid
• Loading skeletons
• Tag-based filtering

​

Empty and Error States

• No tags available
• No asset tags available for the current library contents.
• No objects found
• Try adjusting your search terms or filters to find the objects you're looking for.

​

Selection Behavior

Selecting an asset briefly highlights the card, then starts loading and placement. The dialog closes when insert succeeds.

​

Hierarchy Panel

The hierarchy panel shows the scene tree and supports object-focused navigation. Hierarchy panel for browsing, selecting, and organizing scene objects.

​

Key Capabilities

• Search objects by name
• Expand and collapse nested objects
• Select an object
• Rename an object by double-clicking it
• Toggle object visibility
• Open the object context menu
• Resize the panel width

The hierarchy panel width is persisted locally, so the editor reuses your last chosen width in later sessions on the same browser.

​

Search Behavior

• Search placeholder: Search objects...
• Shows match counts such as 1 match or 3 matches
• Esc clears the search and removes focus
• Arrow keys move through matches
• Enter selects the active match

​

Empty States

• No Objects Added
• Add objects to see them here
• No matching objects
• Try a different search term

​

Hierarchy Context Menu

The hierarchy supports:

• Cut
• Copy
• Paste
• Paste as Child
• Duplicate
• Delete
• Add Object
• Create Empty

For child objects that are still part of their original imported hierarchy and have not been manually reparented, Cut, Copy, Duplicate, and Delete are disabled. Additional restrictions also apply to Initial User Position.

​

Selecting and Organizing Objects

Users can select objects from either the viewport or the hierarchy. The hierarchy is the main interface for:

• Expanding nested assets
• Renaming objects
• Checking visibility
• Working with parent-child structure

The app restricts destructive actions for Initial User Position and for child objects that still belong to an imported model’s original hierarchy, such as nested meshes or groups from a GLB that have not been manually reparented.
