Introduction / Context:
Working drawings are the authoritative set used by fabrication, assembly, inspection, and service. Even with model-based definition growing, many organizations still depend on drawing packages to convey requirements precisely and legally.
Given Data / Assumptions:
- Drawings may be 2D derivatives of 3D CAD or fully annotated models.
- They include assemblies, details, BOMs, and notes.
- They support contracts and quality systems.
Concept / Approach:
A working-drawing set integrates assemblies, detail drawings, standards references, revision control, and specifications. It communicates geometry and requirements, ensures interchangeability, and provides a legal basis for procurement and inspection.
Step-by-Step Solution:
Define the product structure (assemblies and items).Create detail drawings with tolerances and materials.Prepare assembly drawings with item balloons and a BOM.Release the controlled package through PLM for production use.
Verification / Alternative check:
Audit a released job traveler: it references the working-drawing set and revision for the build.
Why Other Options Are Wrong:
Incorrect: Minimizes the role of drawings in manufacturing.Only 3D models are used / Applicable only to aerospace: Most industries still rely on controlled drawings or MBD with clear standards.
Common Pitfalls:
Relying on informal sketches instead of controlled documentation.Unaligned models and drawings causing manufacturing confusion.
Final Answer:
Correct
