Applying Media to Surfaces

You must select a surface before you can apply media. This lets you apply a new media to an existing surface. You cannot apply the back clip to a surface. The back clip is used as the background.

To apply media to a surface:

1. Select a surface by clicking one of the surface edges in the scene or changing to Schematic view and clicking the surface icon.
2. In the Media list, select the media to which you want to apply a surface.
3. Click Apply.

   The selected surface is applied to the selected media.
