Auxiliary view offsets: the offset used to transfer the front-to-back sizing (width) into an auxiliary view should match which corresponding measurement taken from the top view?

Introduction / Context:
When constructing auxiliary views, distances measured in one principal view are transferred to the auxiliary using offsets that preserve true size along axes that are parallel to the projection direction. Correct identification of which dimension to carry over prevents scaling errors.

Given Data / Assumptions:

• Width is conventionally the front-to-back dimension.
• The top view displays width and length; the front view displays height and width.
• We are transferring the width component into an auxiliary derived from the top/front system.

Concept / Approach:
Because the top view measures width accurately (assuming standard orientations), the auxiliary's width offset should equal the width measured in the top view. This preserves true size along the correct axis when projecting to an auxiliary plane parallel to the inclined face.

Step-by-Step Solution:

Verification / Alternative check:
Dimension the auxiliary and compare the width with the model or known size from the top view; they should match exactly.

Why Other Options Are Wrong:

• Height: Primarily controlled by front/right views.
• Length: Read from front/top along the horizontal axis, not the front-to-back axis.
• None of the above: Incorrect because width is the directly corresponding measure.

Common Pitfalls:
Mislabeling axes after rotating or reorienting views; always verify the axis directions before transferring offsets.

Final Answer:
Width
