Does anyone know of a way (or an mbx) that would allow one to draw a boundary around a 
set of
points based on specific (user defined) criteria. I would envision the following 
example representing
the problem that faces me:

        Site Name/ID    RxLev           RxQual
        DFW001  12              5       
        DFW002  10              1
        .       
        .
        .
        DFW004  18              12
        DFW005  20              14

Where I would want a boundary drawn around and encompassing points with an RxLev < 18 
and another
boundary around points that had an RxQual > 10. Any suggestions or help would be 
greatly appreciated.
TIA,

Frank
