## What is Rollwise?

Rollwise is a pipe layout calculator built for fitters, welders and apprentices who are tired of renting their math.

Enter your numbers the way you read a tape: feet, inches and sixteenths. Rollwise gives you travel, run and an actual cut length with the elbow take-outs already subtracted. A live isometric drawing labels every number so you can check the answer and show it to your apprentice.

FREE
• Simple offsets at 45°, with B16.9 elbow take-outs and root gap subtracted
• Grade and slope: drop from run, or slope from drop, in inches per foot, percent and degrees
• Feet-inch-fraction scratch calculator

ROLLWISE PRO (one-time purchase)
• Every angle: 11-1/4°, 22-1/2°, 30°, 60° and any custom angle
• Rolling offsets: true offset, travel, run, cut, and how far to roll the fitting off plumb, with a known-angle or known-run solve
• Parallel offsets for 2 to 6 pipes on equal spread, with the stagger mark for every pipe
• Miter cutbacks for 2- to 6-piece miters: cut angle, cutback and segment lengths
• Elbow take-out tables: long-radius 90° and 45° and short-radius 90° butt-weld elbows, 1/2" to 48"
• Your own fitting profiles for grooved, threaded or socket-weld fittings: enter your manufacturer's take-out once and use it everywhere
• Exact trig or handbook constants (1.414, 2.613 …), with a clear badge showing which mode you're in
