This command adds a line of final exit to a building. An exit can be added to either a floor or staircase but normally exits are not added to staircases. The location, name and width of an exit line can be specified in the dialogue box which appears. The user should then click into the window which is to contain the exit line. When the mouse points to a valid area of the floor/staircase, an exit line will appear when you click the left mouse button. You can ‘click-and-drag’ the exit with the left mouse button, and rotate it by using the right mouse button.
