Currently PDS relies on AutoCAD's Proxy Entity functionality to display the markings/signs in drawings when they are opened by a 'non Line/Sign user'. This means they can view the objects but not interrogate them. The ability interrogate the properties of the Line / Sign objects would require Causeway to produce what is called an Object Enabler. This is a small app that would be downloaded to the 'non Line/Sign user's PC and control the amount of object data available to view in the AutoCAD Properties window
