You may edit the location of home rooms with the mouse, after selecting them in the home plan. To select one room in the plan, click on it. To select multiple rooms or multiple objects in the plan, draw a selection rectangle around them, or/and click on them while pressing shift key. To move the selected objects, place the mouse pointer inside the selected box of one these objects then drag and drop them, or press the keyboard arrows. Note that a room is never bound to the walls, windows and doors around it, so you'll have to select a room with these objects to move all them. When one room is selected in the plan, you may move any of its points, with the point indicators that appear at each point of the selected room. You may also move the text displaying its name and the one displaying its area, if they are them visible.

1. 2... | The point indicators shows the points you can drag to move a point of the room.
3. | The name indicator shows the point you can drag to move the name of the room.
4. | The area indicator shows the point you can drag to move the area text of the room.

When the mouse pointer is upon one of these indicators, it changes to indicate you can drag and drop that point or text to move it. While you press the mouse button, alignment lines and the magnetism activated on wall intersections will help you to find a room corner or an other location. The rooms modified with the mouse are drawn simultaneously in the plan and in the 3D view. The name and the 3D attributes of a room may also be edited thanks to its pane, that will appear after a double-click on it in the home plan, or by choosing Plan > Modify rooms... after selecting it. In the room pane, you may change the name of the selected room and whether its area should be displayed in plan or not. You may also choose whether the floor and the ceiling of the selected room should be displayed in the 3D view, and set their color, their texture and their shininess. When the selected room touches or is very close to one or more walls, the room pane displays also Wall sides around room and Wall sides baseboard sections that will let you choose the color or the texture of the side of the walls lying along the room or in the room, as well as their baseboard when the Add baseboard option is selected. If necessary, select the Recompute walls option to automatically split the walls spreading along the other nearby rooms.

• | If you want to modify the name or the 3D attributes of a set of rooms, select these rooms and choose Plan > Modify rooms.... The values of the attributes that are different from one room to another in the selected rooms set, will appear blank in the rooms pane.
• | Use the menu items of Plan > Modify text style submenu to change the size or the style of the texts displaying the name and the area of the selected rooms.
• | You may add a point to an existing room by placing the mouse cursor where the new point should be added, then choosing Add point to room in the contextual menu of the plan. Similarly, you can delete the point of a room under the mouse cursor by choosing Delete point from room in the contextual menu of the plan.
• | If you want to set different colors or textures on different parts of the floor of a same room, create a room for each part and change their color or texture.
• | The elevation of the floor of a room is always equal to the elevation of the level the room belongs to (or 0 if no level was added to home). If the room isn't at the last level, the elevation of the ceiling will be equal to the elevation + the height of the level it belongs to. Otherwise, the height of the ceiling of a room is computed at each point of the room, and the height at each of these points is equal to the height of the closest point of a wall. This allows to create the ceiling of a garret when you set different heights at the start and end points of sloping walls. When the Flat ceiling only option is selected, the ceiling is always flat and placed at the elevation of the highest wall in the level. Unselect this option to try the ceiling of a garret (works only for rooms with a simple shape).
• | The ceiling of a room is visible only from below, meaning you'll be able to see it only when Virtual visit is selected. This allows you to always see the interior of the edited home when Aerial view is selected, whether Display ceiling check box in room pane is selected or not.
• | If you want to disable the activated magnetism on wall intersection points and for the angles of the lines you draw, disable the magnetism in the preferences pane or while moving points, hold down the Alt key under Windows, the cmd key under macOS or the Shift + Alt keys under Linux.
• | If the objects selected in the plan contain walls, rooms, furniture, dimensions, polylines and texts, all these objects will be moved with a drag and drop or the keyboard arrows. If you keep the Ctrl key (or under macOS, the alt / option key) pressed while you drag and drop these objects, they will be duplicated.
• | The unit displayed by default for the area 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.
