A drafter is like a person who draws a picture but instead of drawing a picture of a person or a tree or a house, they draw pictures of things that people build or make. They use special tools, like a pencil or a computer program, to make these pictures very detailed so that other people can understand exactly what the thing they are building or making will look like.
For example, if someone wants to build a big new building, they might hire a drafter to draw a picture of what the building will look like. The drafter will make sure to include all the important details, like how many floors there will be, how many rooms there will be, and how big each room will be. They might also draw pictures of the inside of the building, like the elevators and staircases.
These drawings are very important because they help the builders and engineers know exactly what they need to do to make the building. They can use the drawings to figure out how much material they need, like how many bricks, how much concrete, and how many windows. They can also figure out how to make sure the building is safe and will not fall down.
So, to sum it up, a drafter is someone who draws very detailed pictures of things that people build or make so that other people can understand what they will look like and how they will be made.
