What type of line indicates a cut through a solid object in drafting?

A section line is used in drafting to indicate a cut through a solid object. When creating technical drawings, section lines are drawn along the area where the object has been sliced, allowing viewers to see the internal features and details that would otherwise be hidden from view. This type of line is particularly important for communicating the interior layout of complex designs, such as the arrangement of components within a mechanical part or the cross-section of a structural element.

Each specific line type serves a distinct role in technical drawings. A hidden line, for instance, denotes edges or outlines that are not visible from the current viewing angle, while a phantom line represents a temporary object or an alternate position. A dimension line, on the other hand, indicates the measurement of an object, helping to convey sizes and distances precisely. Section lines, therefore, play a unique role in illustrating the depth and complexity of designs, making them essential for clear communication in engineering and design.
