#AU2013 Wish 1 Granted!

Matt asked to “duplicate scope box across models”. Open the source file (in this case named “scope boxes.rvt”), then activate the target document and run the macro.

public void CopyScopeBoxBtwDoc()
{
    Document doc = this.ActiveUIDocument.Document;
    Application app = this.Application;

    string filename = "scope boxes.rvt";

    Document sourceDoc = app.Documents.Cast<Document>().FirstOrDefault(q => q.PathName.EndsWith(filename));

    if (sourceDoc == null)
    {
        TaskDialog.Show("Error", "No open document named " + filename);
        return;
    }

    ICollection<ElementId> elementsToCopy = new FilteredElementCollector(sourceDoc).OfCategory(BuiltInCategory.OST_VolumeOfInterest).ToElementIds();

    using (Transaction t = new Transaction(doc,"Copy Scope Box from " + filename))
    {
        t.Start();
        ElementTransformUtils.CopyElements(sourceDoc, elementsToCopy, doc, Transform.Identity, new CopyPasteOptions());
        t.Commit();
    }

}
