Using the Structure Scanner and Bulldozer
Scanning a Structure
Hold the Structure Scanner and use it on a placed prefab to inspect it. This is the tool you reach for when you want to confirm what you are looking at before upgrading or clearing it. Scan first, then decide whether to promote the building with an Upgrade or remove it.
Clearing with the Bulldozer
Use the Bulldozer to remove structures you no longer want. The Creative Bulldozer is the unlimited variant for testing or creative play. Point it at the build and clear it, then place a fresh structure item on the cleared ground. This is the fastest way to swap a House for a Modular House or replace a Farm with an Improved Farm when you would rather start clean than upgrade in place.
Marking and Rebuilding
Lay down Boundary Block to outline the area you intend to clear so you do not bulldoze past your target. After clearing, place the new structure and finish it with the appropriate block set. For farms, that means Farm, Improved Farm, or Advanced Farm, plus Crate of Carrots, Crate of Potatoes, Crate of Beets, Bunch of Carrots, Bunch of Potatoes, Bunch of Beets, Carton of Eggs, or Clutch of Eggs for produce storage. For storage-heavy builds, drop in a Compressed Chest or Wooden Crate.
