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
