What type of drawing shows the material, size, and shape of a product for manufacturing?

The correct choice is the technical working drawing, which is essential in the manufacturing process as it provides detailed information about the product's material, size, and shape. These drawings are characterized by precise dimensions, specifications, and annotations that guide fabrication and assembly. They often include multiple views, such as top, front, and side elevations, which help in visualizing the product from different angles.

Technical working drawings are vital for engineers and manufacturers because they communicate the necessary details that ensure the product is built accurately and functions as intended. They also may incorporate additional information such as notes on tolerances, finish specifications, and assembly instructions, making them comprehensive documents for production.

In contrast, pictorial drawings typically represent objects in three dimensions but lack the detailed information required for manufacturing. Conceptual drawings are more about the initial visualization and ideas during the brainstorming phase, rather than the specifics needed for production. Scaled models serve to visualize the design but do not provide the precise data needed for actual manufacturing processes.
