GetProjectPosition Method

Gets the coordinates of a point in the ProjectLocation's coordinate system.

Namespace: Autodesk.Revit.DB
Assembly: RevitAPI (in RevitAPI.dll) Version: 22.0.0.0 (22.1.0.0)

Syntax

C# 
public ProjectPosition GetProjectPosition(
	XYZ point
)
Visual Basic 
Public Function GetProjectPosition ( _
	point As XYZ _
) As ProjectPosition
Visual C++ 
public:
ProjectPosition^ GetProjectPosition(
	XYZ^ point
)

Parameters

point
Type: Autodesk.Revit.DB XYZ

Remarks

When getting this value, the North/South, East/West, and Elevation values report the coordinates of the point similar to the Revit command "Report Shared Coordinates". To get the values of the transformations applied by this project location, pass XYZ.Zero.

If the project has acquired shared coordinates from a linked model, the shared coordinate transformation will be reflected in the coordinates of the transformed point returned by this property.

Examples

Copy C# 
//get and set the value of the projectlocation
public ProjectLocation GetProjectLocation(Autodesk.Revit.DB.Document document)
{
    ProjectLocation currentLocation = document.ActiveProjectLocation;

    //get the project position
    XYZ origin = new XYZ(0, 0, 0);

    const double angleRatio = Math.PI / 180;   // angle conversion factor

    ProjectPosition projectPosition = currentLocation.GetProjectPosition(origin);
    //Angle from True North
    double angle = 30.0 * angleRatio;   // convert degrees to radian
    double eastWest = 30.0;     //East to West offset
    double northSouth = 23.32;   //North to South offset
    double elevation = 22.14;    //Elevation above ground level

    //create a new project position
    ProjectPosition newPosition =
      document.Application.Create.NewProjectPosition(eastWest, northSouth, elevation, angle);

    if (null != newPosition)
    {
        //set the value of the project position
        currentLocation.SetProjectPosition(origin, newPosition);
    }

    return currentLocation;
}
Copy VB.NET 
'get and set the value of the projectlocation
Public Function GetProjectLocation(document As Autodesk.Revit.DB.Document) As ProjectLocation
    Dim currentLocation As ProjectLocation = document.ActiveProjectLocation

    'get the project position
    Dim origin As New XYZ(0, 0, 0)

    Const angleRatio As Double = Math.PI / 180
    ' angle conversion factor
    Dim projectPosition As ProjectPosition = currentLocation.GetProjectPosition(origin)
    'Angle from True North
    Dim angle As Double = 30.0 * angleRatio
    ' convert degrees to radian
    Dim eastWest As Double = 30.0
    'East to West offset
    Dim northSouth As Double = 23.32
    'North to South offset
    Dim elevation As Double = 22.14
    'Elevation above ground level
    'create a new project position
    Dim newPosition As ProjectPosition = document.Application.Create.NewProjectPosition(eastWest, northSouth, elevation, angle)

    If newPosition IsNot Nothing Then
        'set the value of the project position
        currentLocation.SetProjectPosition(origin, newPosition)
    End If

    Return currentLocation
End Function
