I love the LATAM Airlines logo and I'd like to learn how to make that "fold" we can see on the edges I marked with those green circles, connecting one line to another:
That could be something "easy" for those who are "nasa-level" on Illustrator, and because of that, you may tell me a good way (maybe the "right" way) to do it. I mostly created type-based logos, but I'm trying to develop myself in creating symbol-based logos. I'm not so good with Illustrator, but that's why I'm here again asking your help so I can improve my skills learning with who are already good at it.
Just a note: once upon a time someone here on Graphic Design stackexchange who highly criticized me for making a question about something I had no idea how to do it, so I'd just ask a favor: if you are not willing to help, don't reply. We're here to help each other and, also, to learn. I've been using StackExchange during my whole professional life, and unfortunately sometimes there are people with no education, you know that.
