Designed in Siemens NX6
A sundial is a device that measures time by the position of the Sun. All sundials must be aligned with the axis of the Earth's rotation to tell the correct time. In most designs, the style must point towards true celestial north (not the north magnetic pole or south magnetic pole). That is, the style's horizontal angle must equal the sundial's geographical latitude. When the sundial reads by shadows, the shadow-casting object - the sundial's gnomon - may be a thin rod, or any object with a sharp tip or a straight edge.
Sundials employ many types of gnomon. The gnomon may be fixed or moved according to the season. It may be oriented vertically, horizontally, aligned with the Earth's axis, or oriented in an altogether different direction determined by mathematics.
My model of sundial is around 1,8 meters high, suitable for gardens and parks (scroll down for download link).
