HistCAD: A Constraint-Aware Parametric History-Based CAD Representation, Dataset, and Benchmark with Industrial Complexity
arXiv:2602.19171v3 Announce Type: replace-cross Abstract: Parametric CAD sequences are reusable because dimensional and geometric constraints govern how parameter changes propagate. Existing CAD generation datasets and benchmarks emphasize reconstruction fidelity, execution validity, or static shape similarity, leaving preservation of design intent under edits largely unmeasured. We introduce HistCAD, a representation standard, dataset, and benchmark for executable parametric CAD with explicit constraints. HistCAD defines an intermediate language independent of CAD software, recording sketch p
The proliferation of AI and advanced manufacturing requires more sophisticated and automated design tools, pushing the boundaries of traditional CAD systems.
This development addresses a critical gap in AI-driven design by focusing on design intent and reusability, which are essential for industrial AI agentic systems and complex engineering workflows.
The explicit incorporation of constraint-aware, parametric history into CAD representations enables AI to understand and manipulate design intent, not just static geometries, significantly improving automation and iteration capabilities.
