Rotating all objects in file using AppleScript

[_Fitterman_]

I am trying to rotate objects in a PDF file.
I open the file before running the script.
If I manually Select All before running my AppleScript, everything gets rotated:

(* =========================================== *)
tell application "Adobe Illustrator"
rotate selection angle -45 about center
end tell
(* =========================================== *)

How can I put the Select All into the script?

Try

set selection to every page item of document 1

Thanks, that works.
