This tool is very useful to clash check a list of Line Numbers in the PDMS/E3D. To check clash of a PIPE in PDMS/E3D, there is independent tool, but In the iDEES, ‘Piping Clash Check’ tool is a subgroup of AVEVA Utilities Form so user can select desired Lines from PDMS/E3D by using iDEES Line List and Iso Index.
