What is the role of dashed lines in sectioned drawings?

• A. To represent boundaries of the drawing
• B. To show hidden lines or features
• C. To indicate cutting planes
• D. To represent surfaces that are not visible

Answer: (C)

Dashed lines in sectioned drawings serve to indicate cutting planes, which are essential for understanding how the object is being viewed in the specific section. When a drawing is sectioned, it represents a cut through the object to provide a clearer view of internal features that would be obscured in a standard view. The dashed lines mark where the imaginary cut occurs, guiding the viewer to comprehend the orientation and location of that section relative to the whole object. This visual cue is essential for engineers and designers, as it communicates critical information about how the internal components are laid out, where additional details can be found, and how the part interacts with other components in an assembly. The use of dashed lines helps maintain clarity within the drawing and assists in visualizing complex structures, ultimately enhancing the design's functionality and manufacturability.
