i find an advantage in cadison software compare with other cad based software is,
simultaneously one can see both plant space and p&id window in screen,, if one selects a particular line in P&ID, the modelled line in plant space is displaying. Like wise one can see valves, as well as service wise. Very nicely the developers made in that software. Would be a great advantage to Plant 3d users, if this type of function available in Plant3d.
