ifc-structural -- bounded structural-analysis semantics.
This crate exposes schema-resolved borrowed projections for analysis models,
load/result groups, idealized members and connections, applied actions, core
static load values, and their relationship graph across IFC2X3, IFC4 and
IFC4X3. Selected analysis models, loads, members, connections, actions, and
member/activity relationships can be staged through ifc_model::Transaction.
It does not solve structures, generate FEM meshes, evaluate geometry, or claim computed reaction/result authoring.
