Item	Used to
Region
Inside	Set the block region of interest as being inside the perimeter of the block.
Outside	Set the block region of interest as being outside the perimeter of the block.
Condition
Enclosed	Set an enclosed condition for the block. Only those objects that wholly fulfil the region condition will be considered as satisfying the block (i.e. totally inside or totally outside).
Overlapped	Set an overlap condition for the block. Objects that overlap the block perimeter will also be considered as satisfying the block.
Include Coincident Points	If this is checked then any points lying exactly on the perimeter of the Block will be considered as satisfying the Block. If it is not checked then points coincident with the perimeter will not be considered to satisfy the Block.
