As all of piping designers may know, one of the biggest problem in the Piping, is mismatches between Lines in the 3D model and in the Project Line List. By this tool, iDEES can provide two lists which contain Lines which exist in 3D model and not exist in the Line List and vice versa.
If your company uses a 3D software other than AVEVA PDMS/E3D, you can use another tool provided in iDEES.
