Selecting a floor, roof, wall or glass material for a room involves these steps:
Selecting Doors: Doors do not have the type or category classifications. So when selecting a door material there is only the one step of selecting the door material.
Replacing Existing Materials: If you are changing an existing material to another one, the existing type, category or material will be highlighted in light blue in the grid.
Favorites, Recent or Custom Buttons: Click one of these if you want to select from these lists instead of looking through the standard lists.
Cancel Select Material Button: Click this button to return to the Room Data page (or whichever page on which you started) without making any changes.
