## Description

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.
