Fabrication Layout vs Sheet Metal Layout

Fabrication Layout is a professional sheet metal pattern development and fabrication layout calculator for mechanical engineers, fabrication engineers, welders, pipe fitters, estimators, supervisors, students, and industrial professionals. It helps generate accurate flat pattern layouts for common fabrication shapes used in pressure vessels, piping, ducting, storage tanks, process equipment, and heavy fabrication industries. The app reduces manual calculations, improves layout accuracy, minimizes fabrication time, reduces material waste, and increases productivity with easy-to-use engineering calculators.

Ideal For • Mechanical Engineers • Fabrication Engineers • Production Engineers • Planning Engineers • Project Engineers • Estimation Engineers • QA/QC Engineers • Pipe Fitters • Welders • Fabrication Supervisors • Contractors • Workshop Managers • Students and Engineering Trainees Suitable Industries Pressure Vessel Fabrication, Process Equipment, Piping, HVAC Ducting, Sheet Metal Fabrication, Heat Exchangers, Storage Tanks, Structural Steel, Heavy Equipment, Oil & Gas, Chemical Plants, Power Plants, Food Processing, Pharmaceutical Manufacturing, Cement Plants, and General Industrial Fabrication. Fabrication Layout is an essential engineering tool for generating accurate sheet metal flat patterns, cone developments, transition layouts, pipe intersections, miter bends, screw flights, spheres, dish ends, pyramids, and many other fabrication layouts quickly and accurately.

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.
