Sharing & Permissions
Manage who can access an asset.
Access to an asset allows a user or viewer to edit, update, delete, or download the asset. By default, all assets obey the collection-level permission setting. You can further set asset permissions individually for more granular control over edits to your project.
Access permission settings are available on paid plans.
To view and make edits, navigate to 
under the asset window.
Share with people
Add team member emails to allow them access to the selected asset.
Access Requests
Similar to the Collections & Sharing page, here you can manage access requests pertaining to the individual asset selected.
Requesting Access
If you are an editor, commenter, or viewer with access to a collection with a locked asset, you must request access to the locked asset:
To send a request, click on the lock icon. The button and tooltip will update indicating a request has been sent and is awaiting admin approval:
When the request is approved, the card will unlock and normal tile buttons will appear.
If the request is rejected, the card and tooltip will update. If the admin included a note with the rejection request, it will be shown in the tooltip.
If your request was rejected, you cannot take any further action. An admin can still approve your rejected request at a later time.
Access Settings
This determines whether users and viewers can access (modify, edit, delete, or download) this asset.
Locked: Collection users and viewers can only access this asset with an approved request. Collection admins can access the asset and approve or deny requests.
Unlocked: Collection users can access this asset. Collection viewers must request access. Collection admins can approve or deny requests.
Copy to Other Collections
Copy the selected asset to other collections you have access to.
This will create an entirely new asset in the other collection.
Direct Link
Copy the Direct Link of an asset. For any user with existing access to the collection, this direct link will immediately navigate to the collection and open the asset window for the asset.
Public Link
Create and copy a Public Link for an asset. This link lets you share a single asset from your echo3D collection with anyone, even if they don't have an echo3D account. When someone opens the link, they'll see the asset in a dedicated viewer page along with some basic details about it.
To create a public link for an asset, you can configure the following options:
Enabled/Disabled: Control whether the link is currently active. You can disable a link at any time to revoke access without deleting it.
Show Annotations: Choose whether annotations on your 3D model are visible to anyone viewing the link.
Limit on Views: Optionally limit how many times the link can be viewed. Once the limit is reached, the link will stop working. If you don't set one, the link can be viewed unlimited times.
Expiration Date: Optionally set a date after which the link will stop working. If you don't set one, the link will remain active indefinitely.
Note: Add a private note for your own reference. This note is not shown to anyone viewing the link.
You can edit any of these settings or delete the link entirely at any time.
What Viewers See
When someone opens your public link, they'll see a page with your asset and some information about it. For images, videos, and audio files, the asset is displayed using the appropriate player. For 3D models, the asset is displayed in an interactive 3D viewer. Viewers can rotate, zoom, and pan around the model. A toolbar at the top of the viewer provides additional controls:
Recenter: Reset the camera back to the default view.
Play/Pause: Play or pause any animations the model contains (only shown if the model has animations).
Annotations: Show or hide annotations on the model (only available if you enabled annotations when creating the link).
Shadows: Toggle ground shadows on or off.
Snapshot: Download a screenshot of the model as it currently appears in the viewer.
Asset details are shown in a panel next to the viewer:
File type (e.g., GLB, PNG, MP4)
File size
Date created
Date last modified
Polygon count (for 3D models)
Tags
Viewers can also send a note using the text input at the bottom of the page. This note will be sent via email to all administrators of the associated collection.
Important: Viewers cannot make any changes to your asset. They cannot edit details, modify annotations, or download the original file. The public link provides view-only access.
If Something Goes Wrong
If a viewer tries to open a link that is expired, disabled, or has exceeded its view limit, they'll see a message letting them know the link is no longer available.
