Production documentation — drawings issued to build or fabricate Which drawings are formally provided to contractors or shops to perform work and manufacture individual parts or assemblies according to specification?

Introduction / Context:
Turning design intent into deliverables requires clear, unambiguous documentation. The drawings that leave the design office and go to the shop floor or construction site must contain all information needed to fabricate, inspect, and assemble components.

Given Data / Assumptions:

• The question concerns drawings issued externally for actual making/installation.
• Contractors need dimensions, tolerances, materials, finishes, and notes.
• Standards such as ISO/ASME for dimensioning and tolerancing apply.

Concept / Approach:
“Working drawings” is the umbrella term for the released, production-ready set. They include detail drawings (for individual parts), assembly drawings (for how parts fit together), bills of materials, and any special process notes. Their purpose is execution, not merely concept communication.

Step-by-Step Solution:
Identify parts and assemblies requiring fabrication.Produce detail drawings with full dimensions, tolerances, material, and finish.Create assembly drawings with item balloons, BOM, and fit/fastener specifications.Add inspection criteria and notes; release the package with a revision stamp.

Verification / Alternative check:
Quality and procurement can execute based solely on the working-drawing package. If additional modeling is needed to clarify geometry, it is referenced but the controlling documents remain the working drawings.

Why Other Options Are Wrong:

• Assembly details: a subset, not the entire issued package.
• 3D drawings: models aid understanding but are not always the legal manufacturing authority.
• Skeleton assemblies: layout references, not shop documents.

Common Pitfalls:
Issuing incomplete drawings, missing tolerances, or lacking revision control leads to rework and disputes.

Final Answer:
Working drawings
