A single 'panel' is a polygon with added construction kit connectivity elements on each side. A panel can be rendered and described with various shorthands during the process.
In a flat drawing, panels can have colour coded lines and arcs that can be distuingished at a glance. In 3D, only colour coded and offset lines are used.
A panel is not an universal shape, but an implementation of the shape in a known material. The material influences various properties, such as laser kerf compensation, engraving depth and seam tightness. The red line below shows the actual laser path relative to the base shape.
