Instant Structure Snap Mod lets you place complex multiblock machines with a single click. It saves you from placing hundreds of blocks by hand when setting up tech and magic bases. The tool holds your building blocks in its own inventory and shows a hologram before you build. You can rotate blueprints freely and pull materials directly from connected storage networks.
