Using the copy and paste buttons on the elevation profile you can create a new pipeline unitwith identical properties. select the pipe unit that you want to copy in this case it is pipe #1.Click the copy button and then select the cell in pipe unit column with the label andclick the paste button. And a new pipe unit will be added to the profile. Follow the samemethod for the remaining pipe units. This only copies pipe unit view data so you are required toenter the elevation profile data for the remaining three pipes as given below.
