Each model can be configured individually. All changes apply only to the selected model instance. *** # Select a Model for Editing 3D model spawned in the physical environment with an Edit (pencil) button and control handles When a model is placed in the environment: * An **Edit** button (pencil icon) appears near the model. * Selecting the model displays a visible **bounding box**. *** ## Showing the Bounding Box Selected 3D model displaying a visible bounding box for resizing and rotating 1. Click/Tap the 3D model. ### What Happens Next A bounding box appears around the model. You can: * Resize the model * Rotate the model To remove the bounding box: 1. Click the model again. The bounding box disappears. *** # Open the Edit Menu Each model has an **Edit** button (pencil icon). Edit panel opened for a selected 3D model showing Interactable, Animation, Duplicate, Copy Position, Paste Position, and Delete options ### Step-by-Step Instructions 1. Click the **Edit** button. ### What Happens Next An **Edit** panel opens with the following options: * **Interactable** * **Animation** * **Duplicate** * **Copy Position** * **Paste Position** * **Delete** All options apply only to the selected model. *** # Interactable Settings Select **Interactable** from the Edit menu to configure operator interaction behavior. Interactable panel for the selected model with Interactable and Interactable Ghost toggles in their default state Interactable panel with Interactable and Interactable Ghost toggles turned on The Interactable panel includes: * **Interactable** (toggle) * **Interactable Ghost** (toggle) *** ## Enable Interactable When **Interactable** is enabled: Interactable panel with the Interactable toggle turned on for the selected model * The model becomes interactive in **Operator** mode. * When an operator reaches the same step, they can move or interact with the model.
