Hi Product Hunt 👋 I run a small fab shop and kept hitting the same wall: to get a flat pattern from a customer's STEP file, someone needed an expensive CAD seat open just to unfold one part. So we built Bendline. Drop in a .step/.stp part, pick the base face (or let it auto-detect), set thickness and K-factor, and you get a cut-ready DXF with CUT and BEND on separate layers — plus a dimensioned PDF drawing with a bend schedule, an on-screen bend table, and a press-brake CSV. There's an API too, from the entry plan. The whole preview + unfold is free and needs no account — you only pay to download (a £9 pack of 10, or a monthly plan). The geometry engine is the same OpenCASCADE/FreeCAD stack the desktop tools use, just running server-side so there's nothing to install. It's early, and I'd genuinely love feedback from anyone who bends metal — especially where the unfold disagrees with what your brake actually does. Happy to answer anything.
