What is the primary purpose of an assembly drawing?

The primary purpose of an assembly drawing is to illustrate two or more parts fitted together. These drawings are essential in conveying how various components interact and connect with each other during the assembly process. They provide clear visual guidance on the placement, orientation, and relationship between parts, which is crucial for ensuring that all components fit together properly in the final assembly.

Assembly drawings typically include important annotations and details, such as part numbers, notes on assembly sequences, and any necessary dimensions. This helps manufacturers, engineers, and technicians accurately construct or assemble products while minimizing misunderstandings or errors.

In contrast, showing a single part, detailing product specifications, or presenting materials used in production serves different, more specific purposes that do not relate to demonstrating how multiple parts function together in an assembled state. Thus, these functions do not fulfill the primary objective of an assembly drawing.
