Deleting free form graphics in Acrobat Pro

[Beau25693368df45]

I've imported a hand-drawn map into Acrobat Pro and want to edit it by deleting hand-written lines and boxes.  I was hoping to just "erase" what I don't need with my pen.  I saw a You Tube on how to do this and the entire screen of Acrobat Pro is different than mine.  I can't isolate specific areas of the map to work on.  I'm on a 7-day free trial to see f I want to purchase this.

Acrobat is not the tool for this type of job. You should use an image editor, like Photoshop.
