The 3-D Cube Tool creates simple three-dimensional cubic rectangles. To use this tool, position the mouse cursor where the top left corner of one side of your cube will be located. Hold down the left mouse button and drag the cursor to the location where you would like the opposite corner. When your cube reaches the desired size and shape, release the mouse button. Once you have defined the dimensions of your cube’s first side, the 3-D Editor will appear allowing you to rotate and position the object before it becomes a permanent part of your picture.
