To draw polygons, type the POLYGON command and follow the prompts. A good way to draw by giving coordinates is by using polar notation. Select the LINE tool and pick a start point with your mouse. To draw a 133mm X 39 mm rectangle, type @133<0, then type @39<90, then @133<180, then @39<270. The first number after the @ is the distance, the < means angle, and the second number is the angle in degrees. You can make any polygon with this method by changing the angle and the distance. To draw the circle, select the CIRCLE tool, follow the prompts to enter the diameter or radius, and use OSNAP to grab points on the circle.
