1 · Describe the building. Walls tab → the Quick build box. One wall per line, or the whole house:
all: 2x6 9' zip, dbl top schedule: W1 3050, W2 6050, D1 3068, GD1 9x7 box 40 x 28 ← or trace: E 40, S 28, W 20, N 10, W 20, N 18 N wall 40' W1 @ 4' 12' 20', D1 @ 30' E wall 28' W2 c ← c = centered · W1 x3 = three · ? = couldn't read it
Ctrl+Enter builds. Or the Takeoff tab reads the plans. Or paste a JobTread estimate row (Name ⇥ Description).
2 · Check each wall. The strip of chips is your walls — tap one. The drawing is live; Tape shows the layout numbers. Openings: the one-line box (3050 window at 12') or the cards. Corners & ends: what each end runs into. Rake / slope for sloped top plates.
3 · Hand it out. Crew sheets → PDF (one page per wall, big type) · Order (the lumber list, the way the yard reads it) · Crew tab: Today's list and the phone stations (Yard / Cut / Foreman) · 3D: the walls stood together.
Simple / Pro (top right): Simple hides the deep sections — channels, beam pockets, panels, hardware, pricing. Flip to Pro when you need them.
Rules the app builds on: splices on a double stud, bottom and top plate break together, cap laps 4' past · 16d framing, 8d sheathing · jack nailed to the king on the deck · headers, beams and hardware per the plans — the app never sizes structure.
Offline: once it has opened, it runs with no signal. Jobs save on the device; Save job / Load job moves them between people.

Reads the sheet's own text and line work: title, scale, window & door schedules, every wall with its length, and the marks on each wall. Nothing is guessed — lengths are checked against the printed dimensions.
For photos, scans and PDFs with no text layer. Box the walls (or the schedule) first for a sharper read; with no boxes it reads the whole sheet in tiles.
Every note block on every sheet — general, framing, structural, foundation, roof, keynotes, the schedules' notes — and the callouts that give a number. What a note sets is on Job rules, marked “from plans” with the note (your own number on the job still wins). Tick a field note to put it on the crew sheets.
Scan a sheet first. Every wall is editable — tap one to change its length, height, stud or openings. Lengths are outside-to-outside on exterior walls (what the printed dimensions give) and face-to-face on interior walls.
Scanning a sheet with a schedule fills this in. Every mark can be dropped onto an opening, and you can attach the manufacturer's sheet to a mark.
Lengths, areas and counts you take off the sheet. Tap a line to make it a wall. Everything here saves with the job.
Questions answered from this sheet's text and what's on screen — "what's the header over D04?", "list every 2x6 interior wall", "what ceiling height is called out?".
