|  |  | Drawing rooms

To draw rooms, you must first choose Plan > Create rooms or select the Create rooms tool. Create rooms tool You may create a new room or a new surface in home plan using either way: click at each corner of the room, then double-click at its last point or press the Escape key after you added the last point, double-click anywhere inside an existing closed surface (i.e. surrounded by walls). When you draw a room point by point under magnetism activated, a colored point guide will show up to help you click at each corner of the room. A room created with a double click will cover the floor area from wall to wall surrounding the point where you clicked, and will include also the half doorstep of each door placed on these walls. This feature ensures rooms join each other correctly in the 3D view when the doors between rooms are opened. So, unless you want to create a special surface that is not attached to walls (like outdoor paths), you should draw walls and add doors first to your home to benefit of the ability of the software to display alignment guides and to compute rooms including the half doorstep of each door. New rooms are simultaneously drawn in the plan and in the 3D view.
Drawing a room point by point
Creating with a double-click a room that includes an half doorstep
To end the drawing of rooms, choose Plan > Select or select the Select tool (or an other tool). Select tool

• | 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 Mac OS X 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 Mac OS X, 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.
