Build streamlined or organic shapes using a rich palette of curved parts.

Curved parts are organized into subcategories based on the direction of the curve.

Parts curved on the horizontal plane are described as bricks, plates, or cylinders.

Parts curved relative to a vertical plane are curved, arch, or mudguards.

Parts curved in multiple dimensions are dishes, domes, and wedges.
