Thank you for reply. I have checked the included Effect in that post which works for included area. I will try to make something similar for excluded area. But in my opinion, the logic of object translation should be changed in ForestPack, so translation of objects should be done first, before applying area boundaries, to cut the objects which are out of the boundary line. Or there should be an option what to do with the objects beyond the boundary line after applying translation, delete them or keep them. There are Falloff Include and Exclude parameters in Area to tweak the edge. Why couldn't we have Cut parameter there?
