New CAD framework generates B-Rep models directly from parametric surfaces

Researchers have developed ParaCAD, a novel autoregressive framework for generating Boundary Representation (B-Rep) models directly from parametric surfaces. This approach preserves the intrinsic geometric fidelity and parameters of CAD models, unlike previous methods that relied on point- or grid-based representations. ParaCAD generates surfaces with constrained UV domains and then constructs a valid B-Rep by intersecting these surfaces, enabling more accurate and usable 3D designs for downstream applications. AI

IMPACT This framework could improve the accuracy and usability of 3D models generated by AI, enhancing downstream design and application.

    Autoregressive B-Rep Shape Generation with Parametric Surfaces

    arXiv:2607.17093v1 Announce Type: new Abstract: Generative CAD modeling has broad design and application potential. Despite significant advances in Boundary Representation (B-Rep) generation, the dominant representation in CAD, existing methods largely depend on uniformly sampled…
