# Permission levels in CADchat

Learn what Can Edit, Can Comment, and Can View Only allow collaborators to do in a space.

## Permission levels

You assign a permission level when you invite someone to a space, or when updating their access in the **Invite Users** modal.

-   **Can Edit:** Full access. Users can upload files, add and manage 3D models, use drawing and markup tools, place pins and threads, and modify space content.
-   **Can Comment:** Partial access. Users can view content, place pins and threads, and reply to threads. They cannot upload files or modify space content.
-   **Can View Only:** Read-only access. Users can view the 3D model, documents, and whiteboard. They cannot add annotations, upload files, or post threads.

## Tips and edge cases

-   Permission levels apply per space. The same user can have different permissions in different spaces.
-   The **share** and **download** checkboxes in the **Invite Users** modal are independent of the permission level, you can restrict or allow these separately.
-   **General Access** (Anyone with the link) uses the same three permission levels and applies to anyone who opens the link without a direct invite.
-   Space owners always have full control, regardless of which permission level is assigned.
-   If a collaborator cannot upload files, check that their permission is set to **Can Edit**.
-   If a collaborator cannot add threads, check that their permission is at least **Can Comment**.
-   If you cannot change someone's permission, you may not be the space owner.
