How can I get geometry value from levels and grids?

What I want to do is making Bounding Box by geometry value from levels and grids.

I could make function for Bounding Box, but exporting geometry value is difficult.

How can I get elevation from two levels and X and Y coordination from two X grids and two Y grids?
sorry for my bad English I can explain again if you can’t understand my text.
