If you played the demo of my factory builder game MegaFactory, or any other factory builder game for that matter, you know how tedious it can get to build the same chain of machines again and again. Consequently, most factory builders have blueprints, allowing you to build numerous machines in one go. Blueprints are now also a feature of MegaFactory.
I designed it similarly to Satisfactory, in the sense that you cannot just copy-paste from your existing factory. Instead you have to design a blueprint in a separate blueprint design area. Blueprints are limited in size, with 3 different sizes becoming available as you qualify for and purchase the necessary upgrades.

The below animation shows two iron ore to iron bar processing arrays being built with a blueprint. The 5x8 tile blueprint is the smallest blueprint size, the one you first gain access to.
