when i needed to take the measures of an industrial part, i used to use a sheet of paper and a pen to take notes from measurements. and while CADing sometimes the handwriting were unclear and ambiguous and difficult to recognize where they belong. but now i use an app which allows me to take picture from where i want with the favorable angle and then use the arrow with the measure on it. using this app caused more comfort and clarity in my work. i wanted to share this experience.
