Unbend is a sheet metal calculator built for the shop floor, not the office. Type a dimension and the technical drawing redraws live, so you always see exactly which measurement you are editing. BENDING • Bend allowance, bend deduction and flat blank length • Single bend, multi-bend profiles, U channel, Z profile, hem and joggle • K-factor resolved from material and forming method, with a built-in R/T table • Set your own K-factor per material with the custom table (Pro) FLAT PATTERN DEVELOPMENT • Cone, truncated cone, cylinder, truncated cylinder and segmented elbow • Full ordinate table for marking out by hand • Pattern view with zoom and clear line language: solid for cut, dashed for bend BUILT FOR FABRICATORS • Fraction keypad with true stacked fractions, in inches or millimeters • Works completely offline, nothing is sent anywhere • Save jobs and return to them later • Available in 15 languages EXPORT • DXF for CNC, plasma and laser cutting (Pro) • True 1:1 PDF templates with a print calibration ruler (Pro) • Tiled PDF for patterns larger than the page (Pro) • Ordinates as CSV, or share the pattern as an image FAIR PRICING Every calculation is free and unlimited, forever. One single payment unlocks DXF export, 1:1 and tiled PDF templates, unlimited saved jobs and the custom K-factor table. No subscription, nothing renews, and the unlock stays with your store account.
