Research questionHow can face pairing in thin-walled CAD models handle multiple local wall thicknesses without threshold- or order-dependent results?Rule-based pairing can produce different groupings when geometric thresholds or processing order change, especially in models containing several local wall thicknesses. These inconsistencies can prevent reliable mid-surface and shell-model generation.

Latest papersRecent research connected to this question, newest first.MidSurfNet: Learning Face Pairing for Mid-surface Abstraction of Thin-walled CAD ModelsThe source studies face pairing for thin-walled CAD models as a preprocessing step for finite element analysis. Evidence comes from 1,575 manually annotated CAD models, including multi-wall-thickness cases, with downstream mid-surface generation through an industrial API and finite element analyses; broader generalization is not established.research paper · Sep 3, 2026
