When designing buildings you have to create walls. You can do this by representing each section of a wall as a block with a certain width, length and height. The problem is that his takes a lot of time and it is not easy to make modifications because you have to change the position and dimensions of individual blocks. For this reason a special type of extrude operation called
Wall has been added. You specify the position of the walls in the XY-plane by 2D points. Then you enter a width for the wall and optionally a checkbox if you also want to add a floor or a roof. To modify the building you can just add, remove or change points. The wall extrusion also takes care joining walls that are slanted.
