This is why I do not want to automate production of end products: It will just stall the factory.

I want to feed my turrets with ammo but they are far away and apart, its just bad design when you have an overly full ammo belt to them right? Can I prevent expensive product belts from filling up efficiently? I don't want a kilometer of science packs working as a useless buffer. Basically I want some CAD tools for the game Moving stuff around and automatically reconnect belts and stuff. How do I scale out my Factory, meaning double production like iron or double space for the bus without needing to place everything by hand again? I made construction robots but I can not find where to research blueprints or where to create them (in the tutorial the *magically* appear in the inventory).

I am stuck! I don't want to redo everything by hand and I have no more short term goal.
