🔍 Key Concepts

• Phantom line usage in mechanical/shipboard drawings (showing alternate position, motion, or adjacent parts) • Cutting plane line purpose in sectional views (indicates where the object is cut to create a section like I–I) • How break lines are drawn (usually jagged or wavy to show a portion removed to shorten the view)

💭 Think About

• Look at how line F is drawn compared to the line labeled I–I that creates the section view: are they the same type of line or different? • Ask what function line F is serving in the drawing: is it showing where the object is cut, where it is broken off, or an alternate/hidden outline? • Compare the line pattern of F (solid, dashed, long–short–long, jagged, etc.) with the standard drafting conventions you’ve studied.

✅ Before You Answer

• Verify that a cutting plane line normally has arrows and a section label (such as I–I) associated with it. • Confirm that a break line usually looks irregular, wavy, or jagged to show a removed portion, not a regular smooth contour. • Check whether phantom lines are drawn as long dash – short dash – long dash and used to show alternate positions or adjacent parts rather than an actual cut.
