Using the Bulldozer, Boundary Block and Structure Scanner
Clearing Ground
Hold the Bulldozer and use it to remove blocks in your way before placing a structure. The Creative Bulldozer does the same job without consuming the item. Clear trees, terrain and old builds first so House, Modern, Modular House, Farm, Warehouse and the other structures place cleanly.
Marking an Area
Boundary Block marks the edge of a zone you want to keep clear or reserved. Place a line or ring of Boundary Block around a build site, then place your structure inside it. This keeps later builds and terrain from crowding the area.
Inspecting a Build
Use the Structure Scanner on a placed structure to inspect it. Run it after placing House, Improved House, Advanced House, Modern, Improved Modern, Advanced Modern, Farm, Improved Farm, Advanced Farm, Warehouse, Improved Warehouse, Aqua Base, Improved Aqua Base, Town Hall, Watch Tower, Welcome Center, Jail, Defense Bunker, Machinery Tower, Magic Temple, Mineshaft Entrance, Saloon, Ski Lodge, Villager Houses, Grassy Plain or Instant Bridge to confirm the build is complete. Pair the Scanner with the Upgrade item: scan first, then upgrade, then scan again to compare.
