AutoCAD workflow — creating a Cutting Plane line When drafting a Cutting Plane line in AutoCAD to define where a section is taken, which drawing object type is customarily used to create that line and its jogs?
-
Acenter line
-
Bpolyline
-
Cdashed line
-
Dhatch line
Answer
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:
- AutoCAD or similar CAD is being used.
- Standard linetypes and annotations are available.
- The Cutting Plane may include bends (offsets) and labeled arrows.
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:
- Center line: reserved for axes/symmetry, not Cutting Planes.
- Dashed line: linetype style, not an object choice; still better as a polyline carrier.
- Hatch line: refers to material fills, unrelated to the Cutting Plane path.
Common Pitfalls:Using separate segments that lose alignment, inconsistent linetype scales, or placing Cutting Planes on non-plot layers.
Final Answer:polyline
