Mark out the flat pattern, cut once. Sheet Metal Layout develops the patterns fabricators lay out every day — cones, miter elbows, tees, reducers and square-to-round transitions — right on your phone, fully offline. PATTERNS THAT MATTER • Miter elbow — two-piece, any angle • Cone and frustum — full radial-line development with sector angle • Concentric and eccentric reducers — triangulated true lengths • Round offsets and lobster-back (segmented) elbows • Equal and unequal tees — branch saddle cut depths • Square to round — corner true lengths, laid out LAID OUT RIGHT • Every pattern gives you key dimensions, a schematic and a numbered ordinate / true-length table • A step-by-step "How to lay out" list walks the parallel-line, radial-line or triangulation construction • Copy any ordinate table as text to keep with your job notes • Recent valid calculations stay on your device, ready to rename, reopen, copy or share ACCURATE TO THE METAL • Layout follows the neutral fibre — set the K-factor (mid-wall by default) so bend allowance is built in, not guessed • Pipe mode auto-fills outside diameter and wall from a built-in nominal pipe-size table (½"–12", schedule 40/80) • Sheet mode takes diameter and thickness directly BUILT FOR THE SHOP AND THE FIELD • Inch (fractions to 1/16") or millimetre — one tap to switch • 100% offline — works anywhere, no signal needed • Big controls, screen stays awake, no account • Your inputs never leave your phone ONE-TIME PURCHASE The free version includes the miter elbow, cone / frustum and reducer patterns, plus your three newest saved calculations. Sheet Metal Layout Pro is a single one-time purchase that unlocks the remaining five patterns and your full local calculation history. No subscription. No ads. No feature removals. Ever. Reference layout only. Add your own seams, laps and material allowance, and always verify before cutting.
