How it works

Three steps to a blank.

The whole loop runs in the browser. Load a part, check the unfold, take the DXF straight to your nest or brake.

01

Upload a STEP

Drop a 3D STEP/STP part. It renders instantly in an interactive viewer — no upload wait, no CAD licence, nothing to install.

02

Preview the unfold

Bendline finds the base face automatically, or click to pick your own. See the flat pattern with bend lines, holes, and dimensions before you commit.

03

Download the DXF

Export a production-ready DXF with separate CUT and BEND layers — ready to nest, laser, or fold. Bend metadata travels with it.

Why Bendline

Built for the shop, priced for reality.

Same geometry class as the desktop tools — delivered in a browser, without the seat licence or the subscription trap.

Pay only to download

Preview and unfold as many parts as you like, free, with no account. You pay per export — credits or a small monthly allowance, never a locked subscription just to look.

Brake-ready output

Beyond the DXF: Starter adds a dimensioned PDF drawing with a bend schedule; Pro reads out every bend on screen — angle, direction and radius — and exports the table as a press-brake CSV. So what reaches the brake is a real fabrication drawing, not just an outline.

API from the entry plan

Automate the unfold from your own pipeline — the API is available from the low tier, not walled off behind an enterprise price. See the API docs →
