The flat pattern calculator your fab shop needs — cylinders, cone gores, duct wraps, and more. Fully offline. No account. No ads. Stop laying out cone gores by hand on the table. Stop guessing developed length on a duct wrap. FabCalc generates shop-ready flat pattern drawings and 1:1 DXF files for common fabricated shapes. WHAT'S INSIDE • Cylinder wrap — full shell and partial segments • Half-pipe sleeve — 180° cylinder segments • Cone / frustum gore — annular sector with slant length and arc development • Rectangular duct wrap — four-panel strip with bend lines and bend allowance • Live 2D preview — cut profile, bend lines, roll direction, dimensions • DXF export — AutoCAD R12 ASCII, layered (CUT, BEND, ROLL, TEXT), 1:1 scale • PDF job sheet — drawing, inputs, calculated values, notes • Saved jobs — reopen and edit patterns locally WHO IT'S FOR Fabricators, sheet metal workers, pipe fitters, boilermakers, plasma/laser operators, and shop owners who need accurate flat patterns without desktop CAD. FREE vs PRO Free forever: all shape inputs, live preview, calculated values, warnings, and DXF cut-file export. Pro unlocks PDF job sheets and unlimited saved jobs. One-time purchase or subscription.
