Copy Connected Elements
Copying common layouts to other runs is often painstaking. From first having to copy the parts, to then manually making the connections to the new run, Revit sure doesn't make it easy, but eVolves' Copy Connected tool does. This feature allows you to quickly select standard layouts, copy them to your other runs, and we make the connection for you.
Simply select the Copy Connected button, window select the element(s) to be copied, and click finish. Click on a free end of the element that will be attaching to other elements and click another element to copy and connect them.
