Open Ring

This option allows the user to create an open ring surface. The parameters asked for the creation of this type of surface are the following:

  • The center point of the ring.
  • The minor (inner) radius and major (outer) radius.
  • The angle of the opening, in degrees.
  • The direction of the opening, in degrees, that determines in which direction the opening is facing. A angle of zero degrees means that the opening will be facing in the direction of the positive Y axis, while larger angles of this parameters are interpreted as counter-clockwise rotations.
