Which type of drawing contains both part details and how the parts fit together?

The type of drawing that contains both part details and how the parts fit together is the one often referred to as a Detail Assembly drawing. This type of drawing combines the specific dimensions, materials, and other specifications of individual components (detail) while also depicting how these components integrate and interact within the overall assembly. It serves as a comprehensive guide for the fabrication and assembly process, allowing manufacturers to understand not just how each part looks and is made, but also how they come together to form the finished product.

In comparison, a Detail drawing focuses solely on a single component's specifications without considering its relationship to other parts. An Assembly drawing emphasizes the overall assembly without typically providing in-depth details of each part. A Blueprint is a general term and may refer to various types of engineering drawings, but it does not specifically denote a combination of detail and assembly aspects. Thus, the Detail Assembly drawing is uniquely suited to fulfill the requirement of integrating both critical aspects into one cohesive document.
