What is a cutaway drawing that shows construction and utility details called?

A cutaway drawing that reveals construction and utility details is known as a section. This type of drawing is specifically designed to show a slice or cut through a building or object, providing insights into the internal structure and arrangement of components at a particular location. Sections often display elements such as walls, windows, doors, plumbing, and electrical systems in a way that illustrates their relationship to one another and the overall design.

Sections are vital for understanding how different elements interact within a space and for conveying the vertical dimensions and features that are not visible in plan or elevation drawings. This clarity makes them a key tool for architects and builders to ensure accurate construction and compliance with design specifications. By presenting this detailed view, sections serve as an essential reference for both the construction team and those reviewing the design, ensuring that all aspects are addressed.
