Context: A rotational symmetry geometric restriction forces the optimized model to be symmetric about a specified axis, as shown in Figure 1: You specify the axis of symmetry by selecting the axis of a coordinate system. You can use the global coordinate system, or you can create a datum coordinate system (see Methods for creating a datum coordinate system, for more information). In addition, you must enter an angle that specifies the size of the repeating segment. You can choose to remove frozen regions from the symmetry restriction. |
