This isn't sarcasm, I'm genuinely asking. From the looks of this, you're using it to cross belts over each other, which is precisely what underground belts already do. What am I missing?
Standard underground conveyors have a limited range. If, for instance, you have a massive wall of conveyors and need to cross it, you can use them for that purpose. You could certainly use standard underground conveyors to create a passage through such a wall - I’m not disputing that. This was created purely for my own convenience, there’s no hidden meaning behind it. It’s just that, having recently played Mindustry, I came back to Factorio and realized that a mod like this didn’t seem to exist - even if, admittedly, it doesn’t serve a particularly significant purpose.
