ISegmentZ Interface

Provides access to members that allow simple manipulations of Zs at the segment level.

Description

Allows the Z attributes of the Segment endpoints to be set and returned. Segment attribute awareness is dependent upon the awareness of the higher level collection to which the segment belongs. These methods can be used regardless of the segment's awareness.

Members

Name Description
Method GetZs Get the Zs on the segment's endpoints.
Method SetZs Set the Zs on the segment's endpoints.

ISegmentZ.GetZs Method

Get the Zs on the segment's endpoints.

Public Sub GetZs ( _
    ByRef fromZ As Double, _
    ByRef toZ As Double _
)
public void GetZs (
    ref double fromZ,
    ref double toZ
);

Description

Returns the Z attributes held by the From and To point of the segment.

public static void GetZs()

          {

                  IGeometry  geometry = GetLineGeometry();

  

                ISegmentZ segmentZ = geometry as ISegmentZ;



                 double fromZ;

                double toZ;

 

                segmentZ.GetZs(out fromZ, out toZ);

 

                 //fromZ = 0.224

                 //toZ = 8.29



         }

ISegmentZ.SetZs Method

Set the Zs on the segment's endpoints.

Public Sub SetZs ( _
    ByVal fromZ As Double, _
    ByVal toZ As Double _
)
public void SetZs (
    double fromZ,
    double toZ
);

Description

Sets the Z attributes for the From and To points of the segment. These attributes can be set regardless of the attribute awareness of the segment.

public static void SetZs()

          {

                const double FromZ = 5;

                   const double ToZ = 5;

    

                 IGeometry  geometry = GetLineGeometry();

  

                ISegmentZ segmentZ = geometry as ISegmentZ;



                 segmentZ.SetZs(FromZ, ToZ);



         }
