You can only use this One Time in the SAME ROOM. It will act just like a wall node that you hang a picture on. Sometimes you dont have a wall node where you want one, thats what this will do, fill in the void on the wall and make it easy to remove and place pictures at a single click rather than fooling around with the control and shift keys everytime you want to hang a different picture. This has a central dot and 4 more surrounding it, all capable of holding a picture, convienient for slight adjustments. Place the 5 Wall Node Set anywhere you want. Use the Move tool with the Shift or Ctrl Keys as needed. After you get it where you want it. Click the Padlock Tool and then Lock the wall nodes into place. Now add your wall furniture, picture, sign . etc..
