Import a floor plan gazebo 2.2

Hi Ros users: Is there any way to import a floor plan in gazebo 2.2 on 2d view? I know that in gazebo 5.0 it is possible how you can see in this tutorial http://gazebosim.org/tutorials?tut=building_editor&cat=build_world but i dont know in gazebo 2.2 if it is possible. Thanks!!!
