Creating a 3.8-radius circle around point (40, 0)

1. Choose the option Geometry Create Object Circle.

2. The center of the circle (40, 0) is a point that already exists. To select it, go to Contextual Join C-a on the mouse menu (right button). The pointer will become a cross, which means that you may click on the point.

3. Enter any point that, together with the center of the circle, defines a normal to the XY plane, i.e., (0, 0, 40).

4. Enter the radius of the circle. The radius is 3.8. Two circumferences are created; the inner circumference represents the surface of the circle.

5. Press ESC to indicate that the process of creating the circle is finished.
