Technical Drawing — For many simple, symmetric, or prismatic parts, a single orthographic view supplemented by clearly stated dimensions, notes, and standard symbols is sufficient to fully describe the object for manufacturing and inspection.

Introduction / Context:
In technical drawing and drafting, not every component requires the full set of multiple orthographic views. For simple objects—especially those with symmetry, prismatic shapes, or features that can be fully dimensioned from one direction—a single view enhanced by notes, symbols, and precise dimensions can fully define geometry and intent.

Given Data / Assumptions:

• Object is simple (e.g., symmetric block, plate with holes, turned shaft).
• All features can be unambiguously located and sized from one primary view.
• Standard conventions (tolerances, surface finish, material) are stated in notes.

Concept / Approach:
The core idea is sufficiency of information. If one view plus dimensions communicates size, location, and relationship of all features without ambiguity, additional views are redundant. Standards permit single-view drawings for such cases when clarity is preserved.

Step-by-Step Solution:
1) Identify whether all features project without ambiguity in one view.2) Add complete dimensions (sizes, positions, depths as needed using notes).3) Specify material, finish, and tolerances in the title block or general notes.4) Verify that no hidden geometry remains unclear.

Verification / Alternative check:
Ask whether a machinist could make and inspect the part from the provided data. If yes, the single view is adequate; if not, add an auxiliary or a second view.

Why Other Options Are Wrong:
“Incorrect” ignores well-accepted industry practices; “Only true when scale is 1:1” is irrelevant to definability; “Cannot be determined…” and “Applies only to 3D CAD models” misstate drafting fundamentals.

Common Pitfalls:
Under-dimensioning, omitting depth callouts, or missing tolerances can make single-view drawings ambiguous. Always perform a manufacturability check.
