Hello, i think that the tools at our disposal to building lines are a bit lacking.

I'd like to plan a line by entering a "build mode" with the ability to modify the path by clicking on it and drag/pressing keys to translate horizontally and vertically the belt/pipe, creating lifts when needed and when done building it by pressing a "build" button on screen. this could be unlocked by advancing in the technology tree (maybe after computing?). this way could be a middle/late game tool for complex factory construction.

P.S. I wonder if we could also build underground belt/pipes (locked again in a research) and a way to build them without breaking realism immersion, like a specialized city module that sends out construction crews with assigned excavators, trucks and workers. Maybe this could be a difficulty option in a new game for building everything adding another realism challenge
