how can I measure distance and save in to a variable value?

[tec.nacks]

is there a way o measure the distance between two lines and save the value into a variable?

Like measure the value of distance between Fib level 1 and Fib level 0 then save the distance value in to variable to use in another scenario

I replied to this into your other thread. Do you really need the lines? The bot cannot see them.
