SM Offset is a field calculator built for sheet metal workers, HVAC fabricators, and pipefitters who need exact offset math without the guesswork. Punch in your numbers and get the cut length, arc lengths, elbow centerline, and total offset length, all in real tape-measure fractions. Built for the shop floor and the jobsite, it works 100% offline. No signal, no problem. ROUND • Two-elbow offset — cut joint, elbow takeout, and arc length for a flat offset • Rolling offset — rise and roll combined into one true offset, with cut length to match RECTANGULAR • Duct fitting offsets from width, throat radius, and fitting angle • Standard angles (11.25°, 22.5°, 30°, 45°, 60°, 90°) or your own custom angle • Live results: cut joint, elbow centerline length, and exact offset length WHY TRADES TRUST IT • Every formula is cross-checked two ways • Results in real fractions, not ugly decimals • Fast, dark, glove-friendly interface Whether you're laying out ductwork in the shop or solving an offset on the roof, SM Offset gives you numbers you can cut to.
