There are two reasons why you might not be able to tile the floor. In the first case the floor has been deleted which affects both the 2D and 3D view, in the second the Visibility settings in the 2D view are set to hide tiles.
Reason 1: The floor has been deleted
If the floor has been deleted it will show as a white space in 2D and all the walls will be showing in 3D stopping the user from entering the room.
To restore the floor,
- Right/click one of the walls.
- Select Renew floor from the object menu.
Reason 2: Visibility settings
A second reason tiles may not show on the floor in the 2D view is if the Visibility settings are set to hide tiles.
To check this,
- Click on the Adjust visibility settings icon
on the View tab at the right-hand side of the screen. - Check under Object visibility that Tiles is checked.
