What is a drawing that shows the interior of an object as if it were cut in half called?

A drawing that displays the interior of an object as if it has been cut in half is known as a sectional view. This type of drawing is essential in engineering and design as it provides a clear representation of internal features, components, and layouts that would otherwise be hidden from view in standard exterior representations.

Sectional views assist engineers and designers in visualizing the internal workings and relationships between parts, allowing for a better understanding of the object’s design. This method is particularly useful in complex assemblies where understanding the spatial interaction between components is necessary for effective engineering analysis and design decisions. By illustrating how sections of the object relate to one another, sectional views play a critical role in communication and documentation within engineering fields.
