after some research UI inspector
how can we take advantage of it?
activate application "Preview"
  delay 0.4
set the menuItem to "Draw"
tell application "System Events"
  try
  tell application process "Preview" to click radio button menuItem of radio group 1 of splitter group 1 of window 1
  on error
  try
  tell application process "Preview" to click radio button menuItem of radio group 1 of window 1
  on error errorM

  display dialog errorM

  end try
  end try
end tell
