Copying common layouts to other runs is often painstaking. From first having to copy the parts and then manually making the connections to the new run, Revit sure doesn't make it easy, but the Copy Elements tool does. This feature allows you to select standard layouts quickly, copy them to your other runs, and we make the connection for you.
Select the Copy Elements button, window-select the element(s) to copy, and click finish. Click on a free end of the element that the copied elements will attach and optionally, click another element to copy and connect them.
NOTE: The Copy Elements' predefined selection filter can be modified via the Selection Configuration. Please see the link in the Relevant Articles below.
