Built for the bench and the truck seat

OffsetFit Pipe Desk is a field geometry studio for plumbers, pipefitters, remodelers, and serious DIYers who solve rolling and simple offsets on the truck seat or the bench. Enter center-to-center offset and roll; watch travel length, true fitting angle, and advance update on an interactive diagram with one-tap locks for 22.5°, 45°, and 60°. Pull copper, PVC/CPVC, black steel, and PEX takeoffs from a seeded 90+ card library—each with nominal size, end type, and manufacturer-typical center-to-end—then stack sticks and fittings in the Run Builder. Auto-subtract takeouts, bin cuts into common stock lengths, and export a single-page cut sheet with diagram snapshot, fitting list, remnant summary, and blank field notes. Pure on-device math and reference, fully free and offline-first. Local code, engineer specs, and manufacturer data always supersede app numbers.

Rolling Offset Workspace

Punch in offset and roll; the live diagram returns travel, true fitting angle, and advance. Snap helpers lock 22.5° / 45° / 60° solutions with one tap.

Fitting Takeoff Library

Ninety-plus seeded cards across copper, PVC/CPVC, black steel, and PEX—elbows, tees, street ells, reducers, flanges—with size, end type, and typical center-to-end takeout.

Run Builder Cut Desk

Stack straight sticks plus fittings into a named run. Auto-sum centerline length, subtract takeouts, reorder segments, and duplicate a bay as the next template.

Stick & Waste Planner

Choose stock lengths (10 ft, 21 ft, or metric bars). The app bins cuts into sticks and shows remnant leftovers before you buy or torch.

PDF Cut Sheet Export

One-page job sheet: diagram snapshot, travel/set/advance block, fitting list, stick bins, and blank field lines—shared via system Share Sheet, no account.

Glare-Ready Field Hub

Imperial/metric, fraction or decimal, centerline vs OD, high-contrast diagrams, pinned angle tables, glossary tooltips, and optional widgets for locked presets.

Core loop

From rise/set/roll to a clean cut sheet

  1. Enter offset geometry and optional roll on the live diagram.
  2. Lock angle helpers; read travel, fitting angle, and advance.
  3. Drop real fittings from the on-device library into a run.
  4. Bin sticks, review remnants, export the PDF cut sheet.

Educational field reference only. Always verify dimensions against manufacturer catalogs, engineered drawings, and the authority having jurisdiction before cutting or installing pipe.
