Miter Bend Pro vs Sheet Metal Layout

Miter Bend Pro is a professional engineering calculator for designing segmented miter bends and generating accurate flat pattern development dimensions. It is designed for sheet metal fabricators, pipe fitters, HVAC technicians, welders, mechanical engineers, workshop professionals, and engineering students who need fast, reliable, and workshop-ready fabrication calculations. The app automatically calculates miter bend angles and development dimensions for segmented elbows used in piping, ducting, exhaust systems, ventilation systems, and industrial fabrication. By eliminating manual trigonometry and trial-and-error calculations, it helps improve fabrication accuracy, reduce material waste, and save valuable workshop time. Features • Accurate miter bend angle calculations • Flat pattern development for segmented bends • Workshop-ready cutting dimensions • Supports segmented elbows and multi-piece miter bends • Metric and Imperial unit systems • Automatic internal unit conversion • Imperial fractional dimension support • Fast calculations with an easy-to-use interface • No internet connection required Calculate • Miter Angle • Segment Development Lengths • L0, L1, L2 and additional layout dimensions • Cutting layout dimensions for each bend section Input Parameters • Bend Diameter • Bend Radius • Total Bend Angle • Number of Bend Parts • Development Line Count Ideal For • Sheet Metal Fabrication • Pipe Fabrication • HVAC Duct Fabrication • Ventilation Systems • Exhaust System Fabrication • Industrial Piping • Mechanical Engineering • Fabrication Workshops • Plant Maintenance Benefits • Eliminates manual calculations • Improves fabrication accuracy • Produces precise workshop layouts • Reduces fitting errors • Minimizes material waste • Saves fabrication time • Simple, reliable, and easy to use Whether you are fabricating duct elbows, pipe bends, ventilation systems, exhaust lines, or segmented miter bends, Miter Bend Pro provides accurate layout dimensions and engineering calculations to simplify fabrication and improve workshop productivity. It is an essential tool for professionals involved in sheet metal fabrication, piping, HVAC installation, industrial maintenance, and mechanical engineering.

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 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 — full functionality, never crippled. Sheet Metal Layout Pro is a single one-time purchase that unlocks the remaining five patterns. No subscription. No ads. No feature removals. Ever. Reference layout only. Add your own seams, laps and material allowance, and always verify before cutting.
