|  |  | Editing walls

You may edit the location and length of home walls, either with the mouse or with Plan > Modify walls... from the menu. To edit walls with the mouse, select them in the home plan first. To select one wall in the plan, click on it. To select multiple walls in the plan, draw a selection rectangle around them, or click on walls while pressing shift key. To move the selected walls, place the mouse pointer inside the selected box of one these walls then drag and drop them, or press the keyboard arrows. When one wall is selected in the plan, you may also move its start and end point, with the size indicator that appear at each end of the selected wall.

1. | The start point size indicator shows the point you can drag to move the start point of the wall.
2. | The wall start indicator shows from which point starts a wall.
3. | The wall end indicator shows at which point ends a wall.
4. | The end point size indicator shows the point you can drag to move the end point of the wall.
5. | The roundness indicator shows the middle of the wall you can drag to change its arc extent.

When the mouse pointer is upon the start or end point of the selected wall, it changes to indicate you can drag and drop that point to move it. While you press the mouse button, a tooltip shows the length of the wall. The walls modified with the mouse are drawn simultaneously in the plan and in the 3D view. A wall may also be edited thanks to its pane, by double-clicking on that wall in the home plan, or by choosing Plan > Modify walls... after selecting it. In the wall pane, you may change the coordinates of its start and end points, the colors, the textures and the shininess of its left and right sides, the pattern used to fill it in the plan, the color used to paint its top in the 3D view, its thickness, its height and its arc extent if it's a round wall. You may also add (or remove) baseboards at the bottom of each side by clicking on Modify baseboard buttons. If it's a sloping wall of a garret, choose different heights at its start and end points, and ensure yourself that the Sloping wall radio button is selected. Use the wall start and wall end indicators drawn in the plan on each selected wall to distinguish its left side from its right side.

• | If you want to modify the colors, the textures, the thickness or the height of a set of walls, select these walls and choose Plan > Modify walls.... The values of the attributes that are different from one wall to another in the selected walls set, will appear blank in the walls pane. If among these walls, a wall isn't correctly oriented, select it and choose Plan > Reverse walls direction to reverse its direction.
• | If you want to set different colors or textures on the side of a wall shared by adjacent rooms, divide it in multiple segments at its creation. Afterwards, you may also divide a wall in two walls by choosing Plan > Split wall. If you want to change the color of all the wall sides around a room, draw that room if necessary, and select the color of your choice in the Wall sides around room section of the modification pane of that room. You may also set all the baseboards around a room using the Wall sides baseboard section in the modification pane of that room.
• | If you don't want to compute by hand the length of a wall according to its coordinates, use the field Length at end point. Any change of its value will automatically compute the X and Y coordinates of the wall end point and vice versa.
• | To help you keep walls parallelism, the angle of a wall modified with the mouse is by default a multiple of 15°. You may disable this magnetism in the preferences pane or during mouse move, by holding 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 in length tooltip and the wall pane depends on your country. You may switch to Centimeter, Meter, Millimeter or Inch in the preferences pane.
• | 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).
