Circle/Ellipse draws an ellipse or a circle from two user defined screen positions. The first point sets the center, and the second point determines the edge. To constrain the ellipse to be a true circle, hold the SHIFT key down while clicking the edge point.
The object is hatched if Solid Fill is enabled in the Setup/Draw menu. If the hatching is drawn but not desired, click the right mouse button (undo) to remove it.
