A more thorough explanation:

Definition: A draftsman, also known as a drafter, is a person who creates technical drawings and plans for buildings, machines, or other products. They use computer-aided design (CAD) software or traditional drafting tools to create detailed plans and blueprints.

Example: A draftsman might create a blueprint for a new office building, including detailed plans for the electrical and plumbing systems, as well as the layout of each floor.

Explanation: The example illustrates how a draftsman creates technical drawings and plans for a specific project, in this case, a new office building. The draftsman must have a thorough understanding of the building's design and function to create accurate and detailed plans that can be used by architects, engineers, and construction workers.
