## What is Unbend Flat Pattern Calculator?

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.

## Version history (last 2 releases)

### 1.1.0 — 2026-08-31

• Multi-bend profile now takes 1 to 8 bends. Tap the bend count on the drawing and every new flange and angle arrives with its own measurement.
• A crowded drawing stays readable: the dimension chips tighten up so the part stays visible, and the one you are editing is always drawn on top.
• The result list scrolls instead of pushing "View pattern" off screen.
• Unlock: a clear message and a retry when the store can't be reached, and the export or save you started continues once you unlock.

### 1.0.0 — 2026-08-18

No release notes.
