AutoCAD 2020 – The Polygon Command
You use the Polygon Command to create an equilateral closed polyline. The Polygon command is a hidden command. You can find the Polygon command by typing it in the information centre and pressing enter. When the Help page appears, just click the find icon and a brown arrow will point to the Polygon command in the drop down menu beside the rectangle tool.
