SurfCAD.onlineBOARD DESIGN STUDIO
Browser-based surfboard CAD

Shape surfboards with engineering precision.

SurfCAD is a browser-based engineering editor for defining the complete geometry of a surfboard. Set the principal dimensions, refine the Bézier outline and deck or bottom rocker, and shape rails and bottom contours across seven cross sections. Inspect the resulting form and volume in 3D, save project revisions, create a technical PDF, or export production-ready STL, OBJ and 3MF geometry.

02 / CAPABILITIES

One geometric model.
Every working view.

Each edit updates the same canonical board definition. Outline, rocker, sections and the 3D surface stay connected from first curve to export.

01 / DEFINE

Controlled curves

Edit Bézier points and handles with exact numerical input, constraints and reversible previews.

OUTLINE / ROCKER
02 / REFINE

Seven rail stations

Shape bottom, deck, apex and rail transitions across seven editable cross sections.

SECTIONS / RAIL FLOW
03 / INSPECT

Live 3D inspection

Rotate the generated board and review its deck, bottom, rails and overall proportions from every angle.
