  "abstract": "Current modular design approaches often rely on numerical optimization to satisfy fabrication constraints, which can be computationally intensive and sensitive to initial geometric conditions. This work introduces a parametric design algorithm based on Conformal Principal-Asymptotic (CPA) networks on Minimal Surfaces (MS). This “pre-rationalized” approach enables the rapid generation of diverse shell morphologies while ensuring that construction logic, such as developability and node-orthogonality, is constantly preserved. The method provides a versatile design space for both surface geometry and beam configurations, while also facilitating geometric analyses of assembly-induced stresses. Our methodology is validated through a full-scale experimental timber model, providing a physical proof-of-concept that demonstrates a streamlined workflow for the design and modular assembly of complex elastic gridshells.",
