A nice feature to have for Plant 3D would be a command to Match the Elevation of existing piping.
For example, you have an existing piece of pipe and you are adding new piping from a different location that needs to connect to the existing piping, however if the elevation is off by a small amount (say 1/8") you will get the "Piping - Cannot Determine Autoroute" dialog box. It would be a huge time saver to be able to select the Elevation Grip or another command on the ribbon or right-click menu and then "Match Elevation". Select the other pipe and it adjusts the elevation of the current piping to the exact elevation of the pipe selected to match.
This feature already exists in Civil 3D so there is no reason it cannot be added to Plant 3D.
