Which term is used to indicate where the cutting plane line has cut through material in a drawing?

• A. Auxillary View
• B. Allowance
• C. Section Lines
• D. Interference

Answer: (C)

Section lines mark the surfaces created when a cutting plane passes through a part. When a drawing shows a section, the area where the material has been cut is illustrated with these lines (hatching) to indicate the material on the cut surfaces. This lets you see interior features that aren’t visible in a normal view. The other terms aren’t about indicating a cut through material: an auxiliary view shows true shape of inclined surfaces, allowance refers to added space for manufacturing, and interference relates to parts occupying the same space in an assembly.
