GetProjectPosition Method

Project Location Get Project Position Method

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

Namespace: Autodesk.Revit.DB
Assembly: RevitAPI (in RevitAPI.dll) Version: 25.0.0.0 (25.0.0.0)
Syntax 
public ProjectPosition GetProjectPosition(
	XYZ point
)

Parameters

point XYZ

Return Value

ProjectPosition
Exceptions
Exception Condition
ArgumentNullException A non-optional argument was null
InvalidOperationException Unable to use the project position's transform to calculate the point.
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.

Example 
//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;
}
