Application

Design takeaway

Proactively plan for the long-term curation and preservation of CAD models by utilizing tools that manage representation information and facilitate data layering, ensuring design data remains usable throughout the entire product lifecycle, especially for service-based business models.

How to apply

When developing new products, especially those intended for long-term service contracts, integrate strategies for managing CAD data obsolescence from the outset. Explore and adopt tools like RRoRIfE and LiMMA to ensure design data remains intelligible and adaptable.

Project actions

  • 01Consider the long-term usability of your design files.
  • 02Research file formats and their potential for obsolescence.
  • 03Explore methods for annotating and preserving design data beyond just the 3D model.

Method & Evidence

AimHow can a comprehensive curation and preservation architecture be developed to ensure the long-term intelligibility, adaptability, and reusability of CAD engineering models within evolving product lifecycles?
MethodDevelopment of novel tools and architectures
ProcedureTwo tools were developed: RRoRIfE (Registry/Repository of Representation Information for Engineering) for planning CAD model migration to archival formats, and LiMMA (Lightweight Models with Multilayered Annotations) for layering non-geometric information onto geometric models.

Strengths & Limitations

Strengths

  • +Addresses a critical and emerging issue in product design and service.
  • +Proposes novel tools and architectural concepts.
  • +Highlights the link between digital preservation and business models.

Limitations

The tools developed are specific solutions and may not be universally applicable without adaptation. The complexity of integrating these tools into existing workflows needs further investigation.

Reliability & validity

The reliability of the findings would depend on the consistency of the tools' performance across different CAD models and environments. Validity would be enhanced by testing the tools with a wider range of engineering disciplines and by comparing their effectiveness against established digital preservation standards.

Think critically

To what extent does the reliance on proprietary CAD software inherently limit the long-term sustainability and serviceability of engineered products?

05

Design Principles

"Design for long-term data integrity and accessibility by anticipating format obsolescence and planning for data migration and annotation."

As products transition from simple artefacts to long-term services, the underlying design data must remain accessible and usable. Current CAD formats create a risk of data loss and inaccessibility, impacting maintenance, upgrades, and end-of-life management.

06

What This Means for Your Design

Old CAD files can become unreadable over time, which is a big problem when companies sell products as a service and need to fix or upgrade them years later. This research suggests ways to save CAD files so they can still be understood and used in the future.

How to use in your project

  • 1.Discuss the implications of file format obsolescence on the long-term viability of your design.
  • 2.Justify your choice of file formats by considering their archival potential.
  • 3.Propose strategies for preserving your design data for future reference or modification.
