the input geometry
identifies the surface to be used - if specified null, then the default Ground Surface will be used
Version

GetZsFromSurface(Geometry,ElevationSurfaceLayer) Method
Obtains a geometry that is similar to the given input geometry, where all Z values are populated from an Elevation Surface identified by the given surface name.
Syntax

Parameters

geometry
the input geometry
surfaceLayer
identifies the surface to be used - if specified null, then the default Ground Surface will be used

Return Value

a result that contains a status , plus an output geometry only if the status is favorable

the input geometry is null
this Map does not have a surface named surfaceName
this Map does not have a default Ground Surface (when surfaceName is specified null)
this Map does not have a CIM definition
this Map does not have any surfaces
