ProjectLocation

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

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.
