Parametric CAD Modeling

Ask about this topic

Overview

Parametric CAD modeling studies how to build and change 3D designs through ordered operations, dimensions, geometric constraints, and boundary representations (B-reps), so models remain editable and usable in engineering workflows. Methods include autoregressive and diffusion models for CAD programs, graph-based representations of geometry and design structure, and language-model agents that create or revise code using CAD-kernel execution and geometric feedback. Systems are evaluated on tasks such as generating designs from text or images, reconstructing programs from meshes or drawings, editing construction histories, and assembling parts, with measures of execution, geometric fidelity, constraint satisfaction, and engineering behavior. Although iterative tool use and richer datasets are improving results, models still struggle to preserve design intent, precise dimensions, topology, and editability, especially on complex or unfamiliar designs.
