OMG I am so excited to try this first thing in the morning!
Thank you so much for helping me.
and your question above, about coordinated in ABCD... yes it is always like that
StartX StartY EndX EndY StartZ EndZ Length Angle
For the Searching, Just a Thought. What if you concatenate all StartX StartY EndX EndY so you will have a unique single ID, my concern is,
what if 2 totally different coordinates sums up with the same number?
you are so amazing!
