A Partial Crossover object crosses the range of the group on one side. Partial Crossover objects are available only for similar families. The example below contains a similar range family. F11, F13 is the source, and F21, F23 (not shown in the example) is the target. The deck at D9 (the green rectangle) has the following boundaries: F12, F14, L1, and L9 (L1 and L9 are not shown in the example). In this case, D9 is a Partial Crossover object.
