Point 1: Center of the circle

Point 2: Orientation of the circle (optional)

Point 3: Orientation of the circle (optional)

There are three choices for how you want to save the circle:


Circle: Stored as an actual circle in the drawing.

Plane: Stored as a circular plane with 120 sides,plane circles can be shaded.

Line: Stored as a line entity. This makes it possible to scale the circle or treat it as a line entity with other commands.

Enter the Radius of the circle in the window. To use the same radius as another circle, click the Same As icon. A rubber-band circle shows how the circle will be drawn. Set a point for the center of the circle. Press Enter or set a second point to orient the circle. Press Enter or set a third point to tilt the circle using the first two points as a hinge.

N Segments: When saved as a plane or line, this is the number of segments, into which the object will be divided.
