IEnvelope.OffsetZ Method

Moves the sides z units.

[Visual Basic .NET]
Public Sub OffsetZ ( _
    ByVal Z As Double _
)

[C#]
public void OffsetZ (
    double Z
);

[C++]
HRESULT OffsetZ(
  double Z
);

[C++]

Parameters
Z 
  Z is a parameter of type double

Available with ArcGIS Engine, ArcGIS Desktop, and ArcGIS Server.

OffsetZ shifts the Z attributes of the Envelope. The Depth remains unchanged.

new ZMin=old ZMin + Z
new ZMax=old ZMax + Z
