cut quota extension lines

[spolka]

Good morning my name is Luca di venezia, I've been writing for years.
This is my first post.
as from title, I ask courtsemete if there is a lisp that:
cuts the quota extension lines on the basis of a reference line to be assigned, all maintaining the grip/node of the quota in its original position.

I integrate an image to the request,
thanks to the attention

But isn't it okay to create a style of altitude with lines like you want?

you don't need any lisp to do what you ask
