Offset sections — required bend angles of the Cutting Plane In an offset section view, the Cutting Plane is jogged to pass through multiple features. What are the standard angles used for those offsets or bends?

Introduction / Context:
An offset section lets the drafter show a series of non-collinear internal features in a single section view by jogging the Cutting Plane. Clear, conventional jog angles make the path obvious and avoid confusing the reader.

Given Data / Assumptions:

• The goal is to include several interior features aligned along different centerlines.
• Standards-based linework and annotation are used.
• The section view is projected orthographically.

Concept / Approach:
Offset jogs are drawn at right angles (90 degrees). This convention makes the plane's path unmistakable and easy to track across the parent view, while keeping projection geometry straightforward. A 180-degree “bend” is just a continuation; other arbitrary angles are avoided to reduce ambiguity.

Step-by-Step Solution:
Locate key internal features to capture.Lay out the Cutting Plane as straight segments joined by 90-degree jogs to intersect each feature's axis.Add arrowheads indicating the direction of sight.Produce the offset section; project and hatch cut material accordingly.

Verification / Alternative check:
Examples in drafting manuals show right-angle jogs as the normal method. Using odd angles complicates reading and may suggest a rotated auxiliary view rather than a simple offset section.

Why Other Options Are Wrong:

• 180 degrees: not a bend; it implies no change in direction.
• Either 90 or 180: mixes a valid bend with a non-bend.
• 30, 60, or 90: only 90 is the accepted jog for offset Cutting Planes.

Common Pitfalls:
Failing to align jogs with feature axes, forgetting to maintain consistent linetype/weight, or misplacing arrows and labels.

Final Answer:
90 degrees
