Use the Survey Command Window to modify the elevation of points.
The elevation modification commands are intended to work only with control and non-control points.
To modify the elevation of a single point
MOD ELEV [point 1] (elevation)
To modify the elevation of a multiple points
MOD ELEVS [point 1] [point 2] [elevation]
To modify point elevation by an increment
MOD ELEV BY [point 1] (amount)
or
MOD ELEVS BY [point 1] [point 2] (amount)
This example modifies the elevation of point 2 from 33.528 to 32.004 and then increases the elevation of point 2 by an increment of 10.0. Elevations are in the current units, unless you type a qualifying suffix:
NEZ 1 100 100 30.480
NEZ 2 200 200 33.528
MOD ELEV 2 32.004
! POINT 2 ELEVATION: 32.004
MOD ELEV BY 2 10.0
! POINT 2 ELEVATION ADDED: 42.004
