What is Geometric Similarity Search?

Geometric similarity search is a method for analyzing and identifying similar or identical 3D CAD models, components, or drawings. It automatically compares existing data based on geometric features and organizes the results in a structured similarity hierarchy.

Companies use this approach to improve access to technical information, increase reuse, and make development processes more efficient.

Why is Geometric Similarity Search important?

The volume of technical data in companies is constantly growing. At the same time, complexity, product variations, and time pressure increase - especially in design, costing, procurement, and manufacturing.

Without effective search mechanisms, relevant information often remains hidden:

  • Parts are designed multiple times
  • Drawings are scattered across different systems
  • Comparison data is not available when needed
  • Cost calculations are made without sufficient references

Geometric similarity search creates transparency. It makes it possible to instantly identify similar models, support reuse, and apply existing knowledge more effectively.

How does Geometric Similarity Search work?

The search analyzes 3D geometries based on mathematical features. For each model, it generates a characteristic profile—a geometry signature
— that is independent of naming, file structure, or classification.

The models are then ranked by similarity:

Import of existing CAD data

Automatic analysis and feature detection

Generation of a geometry signature

Comparison with existing models

Sorting by degree of similarity

Visualization and optional alignment with metadata

What are the benefits of geometric similarity search?

  • Fast identification of similar parts
    Models are found within seconds, even across different systems.
  • Avoiding duplicate development
    Existing solutions become visible and can be reused.
  • Accelerated processes
    Design, costing, and production planning gain faster access to relevant references.
  • No data classification required
    The analysis works directly on the 3D geometry—no preparation or predefined structures needed.
  • Technical and commercial data combined
    Integrating ERP, PDM, DMS, and other systems enriches the available information.
  • Improved decision-making
    Reliable comparisons help estimate effort, timelines, and costs more accurately.

Conclusion

Geometric similarity search creates transparency in technical data assets. It enables companies to find parts across systems, increase reuse, and reduce development effort.
The result is shorter processes, lower costs, and a stronger decision-making foundation in design engineering, costing, procurement, and manufacturing.

For efficient processes, transparent information, and better decisions throughout the entire product development cycle
