Collision? range, selection circle

[Sayiain]

Which fields in object are responsible for:
1. Range of the the green circle appearing around selected unit.
2. Range of blocked area for the unit(you know Kodo is blocking more than peon)

I think that 1. is 'Graphics - scale of choice'(or something like that I have polish version).
But 2. I can't find. The only thing I find is the range of following. But the following unit can come closer to the followed one.

Help.

Art - Scaling Value - Changes the size of the model
Art - Selection Cirlce Height - Changes the height at which the selection circle sits (ie. Ground units default 0 while flying units +-200)
Art - Selection Scale - Size the Selection circle around the unit.

Pathing - Collision Size - Determines the area which a unit will "block"
