1//! Reading the bodies of a STEP file (AP203, AP214, AP242 — the B-rep
2//! geometry they share) as descriptions the kernel builds.
3//!
4//! - [`structure`] finds the bodies — every `MANIFOLD_SOLID_BREP`,
5//!   `BREP_WITH_VOIDS` and `SHELL_BASED_SURFACE_MODEL` of every product —
6//!   with their units and, in an assembly, where each part is placed.
7//! - [`geometry`] reads curves and surfaces and builds their NURBS.
8//! - [`body`] reads each body's topology and turns it into a geop body.
9//!
10//! What it cannot read it refuses, naming the entity by type and `#id`
11//! and saying why.
