|  | New rooms must contain at least 3 points to exist (a room created with a click and then double-click will be
            refused). | 
	  
        |  | Creating rooms with a double-click  includes the area of half doorsteps only of the doors with an  elevation
            equal to 0. You may give a small elevation (1 mm is enough) to doors that should be ignored during the computation
            of a room. | 
	  
        |  | To help you draw rooms precisely, use  tooltips, alignment lines and wall intersection point guides. If you
            press the enter key when the plan has the focus, the values displayed in the tooltip will become editable 
            to let you enter with the keyboard the length and the angle of the current segment. If you didn't indicate
            the first point of the room yet, the tooltip will display the coordinates of that point, and from the third point,
            an additional Diagonal text field will let you enter the length of the diagonal which joins the current point to
            the before last point, to help you draw the room by triangulation.Use the up arrow, down arrow or tab keys
            to edit an other value and press again the enter key to confirm the values you entered. If you want to
            use again the mouse to draw the room, simply move it over the plan.

        |  | If you want to disable the activated magnetism on wall intersection points and on the angles of the lines you
            draw,  disable the magnetism in
	        the preferences pane or while drawing,  hold down the Alt key under Windows, the cmd key under macOS or the Shift + Alt keys under Linux. | 
	  
        |  | Once a room is created, you may change its location, its name, its colors and
            textures in the 3D view and whether its area should be displayed or not. | 
	  
        |  | The unit displayed by default in the room, plan rulers and plan grid depends on your country. You may switch
            to Centimeter, Meter, Millimeter or Inch in the preferences pane. If Inch
            is the chosen unit, the room areas will be displayed in square feet, otherwise they will be displayed in square
            meter. | 
	  
        |  | Choose Plan > Zoom in or Plan > Zoom out 
                  to change the plan scale, or roll the mouse wheel forward or 
                  backward while keeping the ctrl key pressed (or under 
                  macOS, the cmd key pressed).  | 
	  
	    |  | Use default Aerial view  while drawing new rooms, you'll get a more useful
            point of view on your home in the 3D view. | 
	  |  | While Create rooms tool is selected, some  tools and menus are disabled. If you need these tools, select the Select	  tool
	  again. |
