Elements that repeat in one or more directions forming a pattern may use this representation to indicate one or more repetition intervals in the form of vectors.
This representation may be used in combination with other parametric representations: 'Axis' for repeating along a curve; 'FootPrint' for repeating within a horizontal boundary; 'Profile' for repeating within a vertical boundary; or 'Box' for repeating within a volume.
Figure 82 illustrates an instance diagram.
