Doors and windows can easily be added to a wall once it is created.

To begin adding doors and windows, select either the Doors or the Windows button on the Building Tab toolbar. The property panel (the left panel) will display a catalog of available doors or windows and some properties that can be set.

To place a door or window, select the desired door or window from the catalog. Once selected, place the mouse cursor over a desired location on a wall and left-click to add the door or window. The same door or window can be placed multiple times in different locations.

Note: Doors and windows must be placed on a currently existing wall.

Properties: Various properties of doors and windows can be set before placing them.
