    Getting Perspective Grid grid specifications

    minimum99 Level 1

      Hi,

       

      Normally you can get various pref parameters via AIPreferenceSuite, but Perspective Grid settings uses its own preference file and there is no API for getting to it. Anyone know how to get the  Perspective Grid settings such as gridline spacing for currently active grid?

          The Perspective Grid parameters are stored in the document dictionary. Here are the keys and their types:

            Thank you very much for this list. Where did you find this list? Are there more constants, since I am looking for various constants that are not in this list for ex: gridline spacing

              Got it, tried CellCount and it gave the grid spacing. So I am good and thank you again.

                You're welcome. The dictionary key list was obtained using Andrew Patterson's Debug Dump Tool, or you can just iterate through the document dictionary yourself.

                  This is funny, but I saw the post about this yesterday and tried to fire up Illustrator to use that very tool to do what what you did Blyskawica, but it was not through the debugger and almost immediately I realized I couldn't see the output!

                   

                  I was in the middle of development on something unrelated so I couldn't fire it up and look for myself, so I'm glad someone did!
