Create a project object by adding a source drawing to a project.
When you add or check in a drawing to a project, you can specify which objects (such as surfaces) in the drawing are to be shared. For more information, see Adding a Drawing to a Project and Checking a Drawing in to a Project.
After a project object has been shared, it is listed in the project’s object collection (such as Surfaces, Alignments, or Pipe Networks) in the Prospector tree.
You can access a project object’s data in another drawing by creating a read-only copy called a reference. For more information, see Creating References to Project Objects.
