ProjectLocation Class

A representation of a specific instance and location of the current project.

Namespace: Autodesk.Revit.DB
Assembly: RevitAPI (in RevitAPI.dll) Version: 18.0.0.0 (18.0.0.420)

Syntax

C# 
public class ProjectLocation : Instance
Visual Basic 
Public Class ProjectLocation _
	Inherits Instance
Visual C++ 
public ref class ProjectLocation : public Instance

Remarks

When using shared coordinates, ProjectLocations can be used to specify specific locations for instances of a linked model. A ProjectLocation keeps track of the position of an instance in relationship to the project's SiteLocation.

By default, each Revit project contains at least one named location, called Internal. Existing ProjectLocation objects can be found by using the ProjectLocations property on the Document object. New project locations can be created by duplicating an existing project location using the Duplicate method, and modifying the location's project position.

Examples

Copy C# 
public void ShowActiveProjectLocationUsage(Autodesk.Revit.DB.Document document)
{
    // Get the project location handle 
    ProjectLocation projectLocation = document.ActiveProjectLocation;

    // Show the information of current project location
    XYZ origin = new XYZ(0, 0, 0);
    ProjectPosition position = projectLocation.GetProjectPosition(origin);
    if (null == position)
    {
        throw new Exception("No project position in origin point.");
    }

    // Format the prompt string to show the message.
    String prompt = "Current project location information:\n";
    prompt += "\n\t" + "Origin point position:";
    prompt += "\n\t\t" + "Angle: " + position.Angle;
    prompt += "\n\t\t" + "East to West offset: " + position.EastWest;
    prompt += "\n\t\t" + "Elevation: " + position.Elevation;
    prompt += "\n\t\t" + "North to South offset: " + position.NorthSouth;

    // Angles are in radians when coming from Revit API, so we 
    // convert to degrees for display
    const double angleRatio = Math.PI / 180;   // angle conversion factor

    SiteLocation site = projectLocation.GetSiteLocation();
    prompt += "\n\t" + "Site location:";
    prompt += "\n\t\t" + "Latitude: " + site.Latitude / angleRatio + "��";
    prompt += "\n\t\t" + "Longitude: " + site.Longitude / angleRatio + "��";
    prompt += "\n\t\t" + "TimeZone: " + site.TimeZone;

    // Give the user some information
    TaskDialog.Show("Revit",prompt);
