Thank you for all the explanation, it is much clearer now.

I am just playing around in CAD to figure out the angles and other values that have geometric meaning. I usually use html report and copy paste values as I have only 4 points. I know there are export options, although I haven't found any that enables rotation angles to be exported. Is there any option that can export to CAD software that I missed?

Thanks for all the replies.
