PDMC Collection for Quality Control and Inspection: Using Autodesk Tools in Manufacturing QA

Quality control in manufacturing is often treated as a downstream activity — something that happens after design and production, checking finished parts against drawings. But the most effective quality systems integrate quality thinking throughout the entire product lifecycle, from initial design through prototype evaluation to production inspection. The Autodesk PDMC Collection provides tools that support this broader view of quality, enabling the design, simulation, documentation, and inspection of manufactured parts within a connected environment.

This article explores how the PDMC Collection’s tools — primarily Inventor Professional, Fusion 360, and their associated analysis capabilities — contribute to quality control and inspection workflows in manufacturing businesses.

Quality by Design: Building Quality into the CAD Model

The most cost-effective quality control intervention is designing quality in from the start. A part designed with unrealistic tolerances will be expensive or impossible to manufacture to specification, regardless of how good your inspection process is. Conversely, a part designed with appropriate tolerances, good geometric dimensioning and tolerancing (GD&T) annotation, and thoughtful material selection will be both manufacturable and inspectable.

Tolerancing in Inventor

Inventor Professional includes a tolerance analysis feature that allows you to stack up tolerances across an assembly and predict the variation in a critical dimension or clearance. Instead of adding up worst-case tolerances on paper (or in a spreadsheet), you define your component tolerances in Inventor’s tolerance analysis environment and the tool calculates the resulting assembly variation statistically, using either worst-case or root-sum-square (RSS) methods.

This is enormously valuable for assemblies where multiple components contribute to a critical fit. A bearing housing bore, for example, depends on the bore diameter tolerance, the cylindricity of the bore, the perpendicularity of the bore axis to the mounting face, and the bearing outer diameter tolerance — all contributing to whether the bearing fits properly and runs without premature wear. Inventor’s tolerance analysis lets you assess this before any metal is cut, and adjust tolerances to achieve a specified probability of assembly success.

GD&T Annotation

Geometric Dimensioning and Tolerancing (GD&T) is the international language for communicating tolerances on engineering drawings, standardised in BS 8888 (the UK standard, harmonised with ISO) and ASME Y14.5 (the US standard). GD&T provides a precise way to specify not just dimensional tolerances but geometric tolerances — straightness, flatness, roundness, cylindricity, angularity, perpendicularity, parallelism, position, concentricity, and runout.

Inventor supports full GD&T annotation on its drawing views, allowing you to create drawings that unambiguously communicate manufacturing and inspection requirements. Properly annotated drawings reduce the risk of ambiguity between designer, manufacturer, and inspector — everyone works from the same geometric specification.

Simulation for Pre-Production Quality Assurance

Physical testing of prototypes is expensive and time-consuming. Virtual testing through simulation allows you to identify potential failures before prototyping, reducing the number of physical test iterations required and the associated costs.

Nastran In-CAD for Structural Verification

The PDMC Collection includes Nastran In-CAD, an advanced finite element analysis (FEA) tool integrated within Inventor. Unlike the built-in simulation in Fusion 360 (which is well-suited for routine design checks), Nastran In-CAD provides a more comprehensive analysis capability for complex or safety-critical structural problems.

From a quality control perspective, running Nastran analysis on a new design before release is a form of virtual qualification testing. You can subject the virtual model to the same load cases that physical qualification tests would apply and verify that the design meets the strength requirements. If the analysis reveals that a design is marginally adequate — with a safety factor close to the minimum — you can redesign before prototyping rather than after a failed physical test.

For parts subject to regulatory requirements — pressure vessels, lifting equipment, safety-critical structural components — analysis results may form part of the technical file submitted for CE or UKCA marking, demonstrating that the design meets the relevant essential health and safety requirements.

Fusion 360 Simulation for Rapid Design Iteration

For less critical analyses and during early design iteration, Fusion 360’s built-in simulation environment provides a faster workflow that integrates directly with design changes. Running a quick stress analysis after every significant design change keeps the design in a known state of structural adequacy throughout development, rather than accumulating changes and doing a single analysis at the end of the design phase — by which point significant rework may be needed.

Model-Based Definition and Inspection

Traditional quality inspection uses 2D drawings as the reference document — an inspector measures a part and compares the measured values to the dimensions and tolerances on the drawing. Model-based definition (MBD) is a more modern approach where the 3D CAD model itself, fully annotated with GD&T, is the primary reference. Inspection systems — coordinate measuring machines (CMMs), structured light scanners, and other metrology equipment — can read this 3D model directly and compare measured data to it.

Inventor supports MBD workflows by allowing full 3D annotation of models with GD&T and dimensional tolerances. This 3D PMI (Product and Manufacturing Information) data can be exported with the model in STEP AP242 format, which is the international standard for PMI-carrying STEP files. Metrology software from Hexagon (PC-DMIS), Zeiss (Calypso), and other CMM manufacturers can read STEP AP242 files and automatically generate inspection programmes from the PMI data, dramatically reducing the programming time required for CMM inspection.

Version Control with Vault Professional

A frequently overlooked aspect of quality management is controlling which version of a design is used for manufacturing inspection. Without robust revision control, it is entirely possible for production to be machining parts to an old revision of a drawing while the current revision has a critical change — a different tolerance, a relocated hole, an updated material specification.

Vault Professional, included in the PDMC Collection, is Autodesk’s product data management (PDM) system. It manages the revision history of every CAD file and engineering document in your organisation, enforces controlled release procedures (so only reviewed and approved revisions are available to production and inspection), and provides a full audit trail of changes.

From a quality management perspective, Vault Professional directly supports several requirements of ISO 9001 — the international quality management standard — including document control (clause 7.5), control of design and development changes (clause 8.3), and control of externally provided processes and services. For businesses seeking or maintaining ISO 9001 certification, Vault’s control features make compliance significantly more straightforward.

Part Numbering and Revision Management

Vault maintains a complete history of every file: who created it, who modified it, when changes were made, and what the change description said. When a part is released for production, Vault can control the drawing release to ensure only the current approved revision is visible to manufacturing and inspection. Attempts to use superseded drawings — a common source of quality escapes in organisations without formal revision control — are prevented by the system.

Quality Documentation and Reporting

The PDMC Collection’s design tools generate documentation that directly supports quality processes:

• Inventor drawings — first article inspection (FAI) documentation requires a complete set of dimensioned drawings with tolerances. Inventor’s drawing environment produces these directly from the 3D model, ensuring dimensional consistency between the drawing and the model being inspected against.
• Bill of materials — Inventor automatically maintains an accurate BOM from the assembly model, which forms the basis for incoming inspection records, material traceability documents, and quality plans.
• Exploded views and assembly instructions — clear assembly documentation reduces the risk of assembly errors that would show up as failures in final inspection.

Integration with Inspection Systems

For manufacturers who use CMM inspection, the PDMC Collection models can integrate with the inspection workflow in several ways:

• STEP AP242 export — as described above, for MBD-based CMM programming
• Reference model for comparison — 3D scanners and optical CMMs can compare a scanned physical part to the CAD model directly, generating colour deviation maps that show where the physical part deviates from the nominal design
• CAD import into metrology software — most CMM software can import Inventor (.ipt) files or STEP/IGES exports directly for use as the nominal reference during inspection programming

Conclusion

Effective quality control in manufacturing is not just about inspection — it is about building quality into every stage of the product lifecycle, from tolerancing during design, through structural verification before prototyping, to controlled release of documentation and comparison of finished parts against the 3D model. The PDMC Collection provides tools that support all of these activities in an integrated environment. For manufacturing businesses taking quality seriously, the collection represents a comprehensive and cost-effective platform for both design excellence and quality assurance.

First Article Inspection Documentation

First Article Inspection (FAI) is the process of verifying that the first production part or assembly conforms to the design requirements before series production begins. FAI is a formal requirement in aerospace manufacturing (defined in AS9102), common in automotive supply chains, and increasingly expected in medical device and precision engineering industries.

The PDMC Collection’s tools support FAI documentation in several ways:

• Balloon-annotated drawings — Inventor can produce FAI-ready drawings with every dimension ballooned (numbered), corresponding to a dimensional measurement report that the inspector completes item by item
• Accurate nominal values — because dimensions are generated from the 3D model, they are guaranteed to match the actual geometry being inspected rather than potentially containing transcription errors from manual dimensioning
• Material traceability linkage — the BOM generated from an Inventor assembly can reference material specifications and certifications, supporting the material traceability requirements of AS9102 FAI

Statistical Process Control and Manufacturing Quality

Quality management in production extends beyond inspection of individual parts to monitoring the consistency of the manufacturing process over time. Statistical Process Control (SPC) uses control charts to track key dimensions across many parts, distinguishing normal process variation from systematic changes that indicate the process is drifting out of control.

While the PDMC Collection does not include dedicated SPC software, the dimensional data from inspection (whether from manual measurement records or CMM reports) can be analysed in Excel to create basic control charts. Microsoft Office 2024 Professional Plus includes Excel, which has the statistical functions needed for basic SPC analysis — mean, standard deviation, control limit calculations, and chart creation — making it a practical tool for small manufacturing businesses implementing SPC without dedicated quality management software.

Supplier Quality Management

For businesses that outsource manufacturing to external suppliers, managing supplier quality is as important as internal quality control. The PDMC Collection supports supplier quality management through:

• Clearly defined design intent — well-annotated Inventor drawings and STEP files with GD&T PMI communicate manufacturing requirements unambiguously, reducing the likelihood of supplier non-conformances caused by drawing misinterpretation
• Revision-controlled drawings — Vault Professional ensures that suppliers always receive the current revision of the design, not an outdated version. Change notifications can be generated automatically when revisions are released, alerting suppliers to updates
• Digital inspection reporting — requesting dimensional inspection reports from suppliers in a format compatible with your own QA records allows monitoring of supplier quality trends over time

The PDMC Collection at €174.99 from GetRenewedTech provides a comprehensive platform for the design, analysis, and documentation aspects of manufacturing quality management, integrating seamlessly with the broader quality management practices of ISO 9001-certified manufacturers and precision engineering businesses.
