### Importing Assets

### Exporting Assets
Exporting assets to echo3D is simple and can be accomplished in two ways: export the scene or export selected objects.
First, enter the file name for the exported asset.
Next, click "Export Scene" to export all the assets or click "Export Selected" to export only the selected items.

**Note:** if you choose "Export Selected", make sure that all the intended elements are selected by looking at the Outliner. If correct elements are not selected when exporting, an empty object will be uploaded.
