Circle Centre

Enter coordinates to adjust the centre of the circle.

Radius

Enter a value to adjust the radius of the circle.

Points

This parameter defines the number of segments of the polygon that represents a 360° circle. For example, if you specify 60 points, then an arc point will be inserted every 6°.

Leave the Points parameter undefined if you want to generate a circle rather than a polygon.
