- NC

Set this parameter equal to the number of cyclically similar images that compose the cavity formed as a result of this symmetry. The angle of rotation (about a point or an axis) used to create cyclically similar images is equal to 360°/NC.

Set TYPE=POINT to create a two-dimensional cavity by cyclic repetition of the cavity surface defined in the model by rotation about a point, l. See Figure 1. The cavity surface defined in the model must be bounded by the line and a line passing through l at an angle, measured counterclockwise when looking into the plane of the model, of 360°/NC to .
Set TYPE=AXIS to create a three-dimensional cavity by cyclic repetition of the cavity surface defined in the model by rotation about an axis, . See Figure 2. The cavity surface defined in the model must be bounded by the plane and a plane passing through line at an angle, measured clockwise when looking from l to m, of 360°/NC to . Line must be normal to line .
