3 Make any of the following adjustments:
• To set the origin point of the square, click a point in the Origin area.
• To specify the exact position of the origin point, type values in the x and y boxes.
• To specify the diameter of a circle, type a value in the Object size box.
• To rotate the circle at a specified angle, type a value in the Angle of rotation box. The origin point of the circle is used as the center of
rotation.
4 Click one of the following:
• Create object — adds a new circle to the drawing window
• Replace object — replaces the selected circle with a new one

To draw or modify a polygon by using object coordinates
1
Click Window Object coordinates.
If you want to modify an existing polygon, select the polygon.
2
Click the Polygon button .
3 In the Object size area, type a value in the Points or sides box.
4 Make any of the following adjustments:
• To rotate the polygon at a specified angle, type a value in the Angle of rotation box.
• To specify the polygon center, type values in the x and y boxes in the Bounding ellipse area. The polygon center is the center of the
bounding ellipse that can be drawn around the polygon. The polygon center is used as the center of rotation.
• To specify the diameters of the bounding ellipse around the polygon, type values in the Object size boxes in the Bounding ellipse
area.
• To specify only one diameter and have the other diameter automatically adjusted in proportion, enable the Proportional check box.
