Geometric Shape Calculator vs SM Offset

Geometry Math Calculator is a practical tool app focused on calculations for 2D and 3D shapes. It helps you quickly compute common geometric values such as angles, lengths, areas, volumes, and centroids. With an intuitive interface, simple input, and clear results, it is suitable for studying, exams, engineering calculations, and daily use. The app includes nearly 50 built-in shape examples across 7 major categories: triangles, circles/ellipses, polygons, cubes, pyramids/frustums, spheres/ellipsoids, and cylinders/cones/torus. Each shape comes with a diagram and clear parameter descriptions—just enter the known values to get accurate results. For the same shape, the app supports multiple input methods to match different known conditions in problems and real engineering scenarios. For example, a triangle can be defined using SSS (three sides) or SAS (two sides and the included angle), ASA, and more. No extra derivation is needed—simply input the parameters to complete the calculation.

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 • Rolling ninety — turn 90° while offsetting, with field-validated math 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.
