This tool is a wonderful tool for checking PDMS/E3D model for any Out of Spec items. As we know, in the PDMS/E3D all PIPEs, BRANches and Components have their own SPEC also in the iDEES there is updated Line List with specified Piping Class, so just for the checking these 4 SPECs must be same and if not, there is problem there.
By this tool iDEES export all mismatches between these 4 specs as Out Of Spec elements. If there is not a valid Line List in the iDEES, there is an option that this tool does not consider iDEES Line List in its result.
