Description
InvalXYFootprint tells the MultiPatch that the XYFootprint it holds may have changed without its knowledge and needs to be recalculated before it can be used. InvalXYFootprint should be called anytime the parts of the MultiPatch are altered without altering the MultiPatch as a whole. Operations which operate on the entire MultiPatch or utilize the MultiPatch interfaces do not require InvalXYFootprint to be called.
