# Upload a 3D model file to a space

Upload, manage, and switch between 3D model files in a space using the Files panel in the 3D Canvas.

## Before you start

You need **Can Edit** access to upload or delete files. See [Understand permission levels](https://help.cadchat.com/en/article/understand-permission-levels).

## Upload a file

1.  Open a space and click the **3D Canvas** tab.
2.  Click **Files** in the left sidebar to open the Files panel.
3.  Click the upload zone or drag and drop a file onto it.

CADchat converts the file for web viewing. Processing time depends on file size, refresh the page if it takes more than a few minutes.

## Tips and edge cases

-   Multiple files can exist in the same space. Each appears as a separate entry in the Files panel.
-   Files are not shared between spaces, each space has its own file list.
-   Assembly files show an **Assembly Details** button in the Files panel for exploring the component hierarchy. See [View assembly details](https://help.cadchat.com/en/article/view-assembly-details).
-   If a file upload fails, check that the format is supported and the file is not corrupted.
