Difficulty: Easy
Correct Answer: polyline
Explanation:
Introduction / Context:
A Cutting Plane line shows where a model is imagined to be cut to produce a section view. In CAD, the object type chosen for this line influences editability, layer control, linetype scaling, and the ease of adding arrowheads and jogs.
Given Data / Assumptions:
Concept / Approach:
Polylines join multiple segments as one editable object, allowing rapid creation of straight segments, offsets, and arrow tails as a single entity. This makes alignment and linetype scaling consistent and simplifies future edits, compared with separate lines or centerline entities intended for axes.
Step-by-Step Solution:
Start POLYLINE on the correct layer/linetype for Cutting Planes.Draw straight segments; add jogs at right angles as needed.Attach arrowheads and labels (e.g., A–A) at ends.Adjust linetype scale and weight for visibility per standards.
Verification / Alternative check:
Editing a polyline (PEDIT) allows quick changes to vertex positions and widths, confirming why polylines are preferred for Cutting Plane graphics in production templates.
Why Other Options Are Wrong:
Common Pitfalls:
Using separate segments that lose alignment, inconsistent linetype scales, or placing Cutting Planes on non-plot layers.
Final Answer:
polyline
