Undefined shading unit

A shading device is a purpose built device to protect from sunlight, natural light, or to screen them from view. Shading devices can form part of the facade or can be mounted inside the building, they can be fixed or operable.

An undefined shading unit is a placeholder shading device for when the type of shading device has not yet been determined.
