🔍 Key Concepts

• Section lining (hatching) on mechanical/shipyard drawings • Standard drafting conventions for showing materials in section view • Difference between symbols for surface finish, machining, and material

💭 Think About

• When a solid part is cut in half in a drawing, what do the angled lines across the cut area usually represent? • Which of the options refers to something that is a property of the whole solid part, not just one face or one operation? • Think about how a draftsman would quickly show what a part is made of without writing long notes on every section.

✅ Before You Answer

• Look closely at how the angled lines are drawn through the whole thickness of the flange, not just on the surface. • Ask yourself whether cutting direction or surface roughness can really be shown by simple angled lines across the interior of the part. • Recall that different patterns and spacings of section lines are a standard way to show different materials on engineering drawings.
