The type of drawing that typically shows detailed specifications for manufacturing is the working drawing. This type of drawing includes all the necessary information needed for a manufacturer to create a part or assembly, such as precise dimensions, materials, and tolerances. Working drawings are essential in the engineering and manufacturing process because they convert design ideas into actionable instructions.

They often contain annotations, notes, and sometimes incorporate multiple views of the same part to provide clarity on how it should be constructed. This level of detail is crucial for ensuring that items are manufactured accurately and to the required standards, minimizing errors in production.

In contrast, concept drawings focus on the overall design and ideas rather than detailed specifications, while presentation drawings are typically used for showcasing a design rather than providing manufacturing instructions. Assembly drawings depict how different parts fit together but are usually not as detailed as working drawings regarding manufacturing specifics.
