Difficulty: Easy
Correct Answer: Phantom
Explanation:
Introduction / Context:Exploded assemblies communicate assembly sequence and relationships. Line conventions ensure every viewer interprets the drawing the same way. The correct line type for indicating alternate positions and assembly paths is critical.
Given Data / Assumptions:
Concept / Approach:Phantom lines (often a long–short–short pattern depending on standard) indicate alternate positions, paths of motion, or relationships in exploded views. Hidden lines show obscured edges; center lines mark axes and hole centers; generic dashed lines may be ambiguous without standard meaning.
Step-by-Step Solution:
Set the exploded view with components offset for clarity.Use phantom lines to indicate the direction and position relationship toward assembly.Label parts with item balloons that correspond to the parts list.Avoid overuse of hidden lines to keep the view readable.Verification / Alternative check:Cross-check your line styles with the company drafting standard to ensure phantom line definitions match plotting conventions.
Why Other Options Are Wrong:
Common Pitfalls:Overcrowding the graphic with phantom lines; keep only those needed to clarify assembly.
