* Equal contribution
BrepDiff is a diffusion-based generative model for 3D Boundary Representations (B-reps). It enables:
- Single-stage generation of valid and diverse CAD models
- Direct editing operations such as shape completion, merging, and interpolation
- Efficient generation, avoiding the complexity and limitations of cascaded pipelines
This repository provides code for training, evaluation, and editing with BrepDiff.
