Question 1 of 27070

Edges on objects not visible in the view shown are represented in blueprints by __________.

🔍 Key Concepts

• Standard drafting/blueprint line conventions used in marine engineering and ship construction drawings • Difference between visible edges and hidden edges on an object • How hidden features (holes, slots, recesses not seen in that specific view) are shown in orthographic projections

💭 Think About

• Ask yourself: In a typical engineering or shipyard drawing, what kind of line shows an edge that exists but cannot be seen from that viewing angle? • Compare which option is normally used for centerlines versus which is used for hidden edges in standard drafting practice. • Think about whether hidden edges are omitted or still shown so that the fabricator/machinist knows the full shape of the part.

✅ Before You Answer

• Recall that visible edges are normally drawn with a thick solid line—eliminate any option that conflicts with that. • Remember that centerlines (to show symmetry or hole centers) use a specific long-short pattern—do not confuse this with hidden edges. • Verify which option describes a line made of short, evenly spaced dashes, commonly taught as the symbol for hidden features in basic drafting standards.

Edges on objects not visible in the view shown are represented in blueprints by __________.

a thick solid line

dashed line having alternating long and short dashes

dashed lines having approximately equal length dashes

Hidden edges are not represented because they are 'hidden'.
