Field notes
The calculator accepts feet-inch-fraction notation as well as millimetres and presents results alongside a live scale drawing, intended to expose a bad input before a cut is made. Its take-out workflow uses ASME B16.9 long-radius elbow tables, while unsupported angles are labelled approximate and can reportedly be replaced with a user’s own measurement. The page also describes offline operation, VoiceOver support, and Schedule 40 and 80 steel pipe data.
