The field book has a Building tab. Lash a sawbuck from four poles and one split wood and set it down where you want to build. Fell a few firs nearby and buck them where they lie: a cabin is made from the logs lying within 8 m of the sawbuck, 2.5 m each, and a wall takes four, a floor three and a roof two. At the sawbuck the book’s button reads Craft and counts the logs beside it.
Select a floor and a pale preview shows where it stands; left mouse sets it. Floors join at their edges, walls go on floor edges, and roofs go over floored bays once walls stand. Q shapes a wall as full, doorway, window or half, the corners notch, openings frame themselves and piers grow to the ground. Tap E on a door to open it, and hold E on any piece to take it back. Besides log walls there are framed walls on a knee-high plinth of split granite: weave a wattle wall in your hands, rive a board wall at the sawbuck, or lay a stone wall.
The same evening the cabin was remade from real things: peeled logs with knots, checks and weathered grain, each course different, a plank door with a Z-brace, iron strap hinges and a latch in every doorway, and a roof of split shakes in courses. For a day each window held a hewn frame with four small panes and a shutter; from October 7 a window is an open frame into the room.
