Split Ring

This option allows the user to create a split ring, that is, a ring surface that is open at two opposite points. The parameters that need to be supplied by the user are:

• The center point of the ring.
• The minor (inner) and major (outer) radius, as in the previous geometries.
• The opening angle, in degrees, that determines how large the openings are. Both openings are created the same size.
• The opening direction, in degrees, that determines how the openings are oriented. An opening direction of 0 degrees means that the openings will be oriented in the direction of the Y axis. Larger angles are interpreted as a counter-clockwise rotation.
