Why is there no auxiliary construction line?

Question

Adobe Illustrator

Why is there no auxiliary construction line when I extend the line? Previously, there was such an auxiliary guide, and it doesn’t matter at what degree the object is located. As you can see, this option only works when I make the line shorter, when I lengthen the option does not work, help is needed!

Answer 1

Because Adobe. When you shorten a line, smart guides tie a point to the line itself, when you lengthen it, there is nothing to tie to. Make auxiliary objects to bind to them.
