MidSurfNet: Learning Face Pairing for Mid-surface Abstraction of Thin-walled CAD Models

This work presents MidSurfNet, a learning-based face-pairing method that couples a learned face-pair scorer with a deterministic face-group composition, and demonstrates practical utility by generating mid-surfaces from the composed face groups through an industrial mid-surface API and running finite element analyses o...
