Wooden Surfboard Designer documentation

Open the app. It starts with a board already loaded, so there is nothing to set up — drag a control point and the shape changes. Nothing is uploaded anywhere: the board lives on your device, and the app keeps working without a connection.

The fastest route to something real: pick a starter template, adjust the outline and rocker, check the volume, then export a 1:1 PDF or a DXF.

The panes

Four views of the same board — outline, rocker, cross-section and 3D. The quad view shows all four at once, and the split view (6, desktop only) stacks any two of them full width; keys 1–6 switch between them. On phones the quad view is not offered — four panes in a phone's width leaves none of them usable — so the editor opens on the outline and keys 2–5 switch.

The sidebar

Four tabs down its edge — Specs, Shape, Build and Reference — so the tool list is always readable and never pushed off-screen by whatever you have open. Specs is the live readout; Shape holds resize, the control-point inspector and the overlay toggles; Build holds board details, fins and the weight estimate; Reference holds trace images, history and the ghost comparison. Inside a tab each tool is a section you open by clicking its header, and a shut section still shows a summary, so you can read a tab without opening anything.

Pinning a tab

The pin in a panel's header keeps that panel on screen while you work in another tab — Specs pinned above Shape, say, so the numbers stay visible while you edit. One tab can be pinned at a time. The double-chevron beside it opens or shuts every section in the panel at once, and the chevron after that folds the panel away entirely, leaving the tab strip and the headline dimensions. Clicking any tab brings it back.

Tools that follow the view

Changing view opens the sections that view is for and shuts the ones it is not — trace controls in the outline and rocker, fins in 3D. It never switches tabs and never hides a tool: once you open or close a section yourself, it stays as you left it. On narrow screens the sidebar becomes a bottom sheet with the tabs laid out as a row.

The menu bar

File, Export, Edit, View, Board and Help. On phones this collapses into a single button that opens the command palette.

A board is three families of curves: the outline (plan shape), the rocker (deck and bottom profiles), and a series of cross-sections down its length. Everything else — volume, area, the 3D mesh, every export — is computed from those.

Each curve is a Bézier spline you edit by dragging control points and their tangent handles. Cross-sections between the ones you have defined are interpolated, so the surface stays continuous.
