ExportPoints Method (String, PointFileFormat, Boolean, Boolean, Boolean)

Exports points to a point file with advanced options.

Namespace: Autodesk.Civil.DatabaseServices
Assembly: AeccDbMgd (in AeccDbMgd.dll) Version: 13.3.1717.0

Syntax

C#

public static uint ExportPoints(
	string pointFileFullName,
	PointFileFormat fileFormat,
	bool useAdjustedElevation,
	bool shouldTransformCoordinate,
	bool shouldExpandCoordinateData
)

Visual Basic

Public Shared Function ExportPoints ( _
	pointFileFullName As String, _
	fileFormat As PointFileFormat, _
	useAdjustedElevation As Boolean, _
	shouldTransformCoordinate As Boolean, _
	shouldExpandCoordinateData As Boolean _
) As UInteger

Visual C++

public:
static unsigned int ExportPoints(
	String^ pointFileFullName, 
	PointFileFormat^ fileFormat, 
	bool useAdjustedElevation, 
	bool shouldTransformCoordinate, 
	bool shouldExpandCoordinateData
)

Parameters

pointFileFullName
Type: System.String
The full path and name of the point file.
fileFormat
Type: Autodesk.Civil.DatabaseServices.PointFileFormat
The file format for the point file. You can get a collection of supported point file formats by using GetPointFileFormats().
useAdjustedElevation
Type: System.Boolean
Specifies whether to adjust the point elevation values.
shouldTransformCoordinate
Type: System.Boolean
Specifies whether to transform the points in the file.
shouldExpandCoordinateData
Type: System.Boolean
Specifies whether to calculate the coordinate data properties of the points, such as degrees, minutes, seconds, and hemisphere for latitude and longitude.

Return Value

The count of CogoPoints that were exported.

Remarks

  1. useAdjustedElevation and shouldExpandCoordinateData are disregarded if they are not supported by the specified point file format.
  2. If the file specified by pointFileFullName already exists, it is overwritten.
  3. If the file specified by pointFileFullName does not exist, it is created automatically.
