Technology Updates

HOOPS Embeddings: Machine Learning Model for Shape Embeddings

This release introduces HOOPS AI’s shape embeddings capability, enabling vector-based similarity search and retrieval for CAD parts using graph neural networks on B-Rep data.

See our Train a Shape Embedding Model page for more details.

New Features

HOOPS AI 1.0-b2 comes with a set of brand new features such as :

Machine Learning & Retrieval:

  • HOOPSEmbeddings:

    • Train a Shape Embedding Model - Core embedding model for converting CAD files into high-dimensional vector representations

      • Built-in model registry for managing multiple embedding architectures

      • Automatic batch and parallel integration for efficient execution

  • FaissVectorStore:

    • Embeddings & Similarity Search - High-performance vector storage and retrieval implementation

      • FAISS-based in-memory indexing for fast similarity search

      • Support for metadata filtering and CRUD operations

      • Persistent storage with save/load capabilities

  • CADSearch:

    • Embeddings & Similarity Search - Unified interface for similarity-based CAD part retrieval

      • Shape-based search (query by CAD file)

      • Index persistence for efficient reuse across sessions

Key Capabilities:

  • Generate embeddings for CAD parts using pre-trained models

  • Build searchable indexes from embedding batches

  • Query by shape similarity

  • Save and load indexes for fast startup

  • Parallel batch processing for large datasets

Other Improvements

  • GraphClassification flow model now uses by default HOOPS Surface Encoder based on a BRep face mesh and a GAT architecture.

  • Flow pipeline during data preprocessing will restart the process pool automatically to maintain a better memory print. Heavy files will be handle in sequential at the end.

  • Dataset Merging is now twice faster.

  • Dataset Loader can now be instantiated with the list of graph files directly.
