Hi Jacob,

thank you for your response. i finally got it working with a cropbox boundingboxXYZ.

trial and error was the key to succes in my case! This is the result for other people to enjoy!

it tests views for titleblock size and creates a list with titleblock types parallel to the view list.

a great result for my first script!
