Abstract
This Technical Specification defines a descriptor-driven method to evaluate shape fidelity between a physical item and its digital twin (DTw) representation. It specifies: - Required terminology, data models, and computation steps for using 3D shape descriptors to quantify 3D shape similarity. - Taxonomy of descriptor classes. - Conformance requirements for metric calculation and reporting. Out of scope: Predictive simulation results (CFD/FEM) and non-geometric fidelity scoring such as motion or performance.
