A designer is a person who makes designs for objects. A fashion designer designs clothing, a web designer designs web pages and an automobile designer designs automobiles. In each case, the designer works with the help of a technician or engineer who understands deeper level concepts of manufacturing and engineering and the designer themself is largely confined to work at a surface level.
More formally, a designer is an agent that "specifies the structural properties of a design object". In practice, anyone who creates tangible or intangible objects, products, processes, laws, games, graphics, services, and experiences is referred to as a designer.
Set Designer designs motion picture or television production sets, signs, props, or scenic effects. Prepares scale drawings for use in construction, modification, or alteration.
