ToGeometry Method (MapPointBuilderEx)
In This Topic
Returns a MapPoint instance representing the current state of the builder.
Syntax

`Public Shadows Function ToGeometry() As MapPoint`

Return Value

Example
Construct a MapPoint
```// Use a builder convenience method or use a builder constructor.

// Create a 2D point without a spatial reference
MapPoint point2D = MapPointBuilderEx.CreateMapPoint(1, 2);
SpatialReference sr = point2D.SpatialReference; // sr = null
bool hasZ = point2D.HasZ;   // hasZ = false
bool hasM = point2D.HasM;   // hasM = false
bool hasID = point2D.HasID; // hasID = false
double x = point2D.X;   // x = 1
double y = point2D.Y;   // y = 2
double z = point2D.Z;   // z = 0 default value
double m = point2D.M;   // m is NaN default value
double id = point2D.ID; // id = 0 default value

// Or use a builderEx which doesn't need to run on the MCT.
MapPointBuilderEx builderEx = new MapPointBuilderEx(1, 2);

// do something with the builder
builderEx.Y = 3;
point2D = builderEx.ToGeometry();
sr = point2D.SpatialReference; // sr = null

// Create a 2D point with a spatial reference
