# Add 3D Models

The second step is to allow users to select one or more 3D models they want to use in their configurator. After selecting the 3d models, you can click the "Preview" button on the top right of the screen to see them in your configurator.

**NOTE:** If you use more than one 3d model in your configurator, once you click "Preview" you will notice that they all "overlap" each other. Don't worry, in the "Create Options" tab you will be able to create options with restrictions (constraints) and hide the ones you want. This will be discussed in more detail in [**Restrictions**](/learning-the-app/products/create-options/restrictions.md).
