What type of diagram shows both external shapes and internal working parts of a system?

A cutaway diagram effectively illustrates both the external shapes and the internal working parts of a system. It is designed to provide a view that reveals the internal components while still depicting the overall structure. This type of diagram is particularly useful in engineering and architectural contexts, as it allows for a comprehensive understanding of how a system is organized internally while also showcasing its external form.

In various fields, such as mechanics, architecture, or electronics, visualizing both the inside and outside of a system can be crucial for understanding how different parts interact. By representing both dimensions in one visual, a cutaway diagram helps viewers grasp the complexity and functionality of a system more effectively than other types, which may only represent either internal workings or external appearances.
