In a big site where you have thousands of supports, piping and cabinets in various floors, It is practically difficult locating installed equipment on site. as the equipment are only liked via schedule, because everything is greyed out, you don't know which floor you are. you can't see a 3D model so that clicking on the item can take you to the schedule, I think synchro site was better in marking out install equipment and getting getting out physical representation of install.
