Client Overview

Our client is a pioneering AI and cloud-based B2B SaaS provider catering to manufacturing companies. Their platform empowers manufacturers to optimize direct material procurement by leveraging AI-driven insights into the true cost of manufacturing products and components globally.

Project Overview

This project focused on CAD geometry, specifically handling 3D models and their geometric properties. By integrating a third-party SDK, our team engineered an intelligent system capable of:

  • Extracting key geometric data (volume, surface area, bounding box values, and fundamental properties).
  • Generating a comprehensive Bill of Materials (BOM).
  • Conducting advanced feature extraction.
  • Identifying Design for Manufacturing (DFM) issues and enhancing manufacturability insights.

Challenges

Identifying Void Portions:

  • The project faced difficulty in identifying the internal voids within 3D models, which are critical for casting.
  • Standard CAD tools did not provide an intuitive way to extract and visualize core voids within the model.

Lack of Direct API Support:

  • No existing API provided a direct solution to detect and extract core voids automatically.
  • Required a customized approach to generate a separate model that represents the void spaces accurately.

Geometric Complexity:

  • Variations in model complexity made it difficult to develop a one-size-fits-all solution for core extraction.
  • Some models contained intricate void structures that traditional detection methods could not efficiently handle.

Maintaining Structural Integrity:

  • Ensuring that the extracted cores maintained the correct geometric relationships with the original model.
  • Avoiding distortions or errors in the extracted void representations.

Computational Efficiency:

  • The core extraction process needed to be optimized for performance, as handling large 3D models could lead to slow processing times.
  • Balancing accuracy with speed was a key challenge in implementing a scalable solution.

Solutions

  • Implemented a B-Representation Algorithm to Detect Holes in the 3D Model:
    • Developed a boundary representation (B-Rep) algorithm to analyze the 3D model’s structure and accurately detect internal voids.
    • Utilized computational geometry techniques to differentiate solid and hollow regions efficiently, reducing error rates in detection.
  • Compared Identified Shapes with the Original Model to Isolate Unique Faces:
    • Implemented a geometric comparison algorithm to differentiate void regions from the main structure.
    • Matched extracted shapes with the original model’s topology to ensure correct identification of void portions.
  • Developed Custom Logic to Determine Adjacent Faces and Edges:
    • Designed an algorithm to analyze model connectivity, identifying relationships between adjacent faces and edges.
    • Ensured accurate tracking of geometric continuity for better structural representation.
  • Closed Open Edges to Form a Solid Representation of the Voids:
    • Applied Boolean operations to bridge open edges and create a fully enclosed core void structure.
    • Maintained topological consistency to prevent gaps or misalignments in the extracted cores.
  • Saved These Solids to Accurately Represent Core Voids Within the 3D Model:
    • Stored the extracted cores as individual solid entities, allowing for precise visualization and manufacturability analysis.
    • Integrated the extracted void models into the overall workflow for enhanced simulation and design validation.
