Given the large number of tools available to Autocad, they can also be grouped into windows called Palettes. Tool Palettes can be located anywhere on the interface, leaning on any of its sides, or floating on the drawing area. To activate the tool palettes, we use the "View-Palettes-Tool Palettes" button. In that same group you will discover that there are a good number of palettes for different purposes that we will be using.
If you need to have the tools of a floating palette in sight on your drawing, then you may find it interesting that it is transparent.
