ifc-alignment
IFC4X3 linear positioning: IfcAlignment with its horizontal, vertical and
cant layouts, referents and stationing, and linear placement. Alignment
curves, transition spirals included, are lowered exactly into the
format-neutral Axiolid geometry model; nothing is tessellated or numerically
integrated.
The openbim-ifc facade also provides it behind its
alignment feature.

Design notes
- This crate is the geometric bridge for alignments, not a road or rail application. Product workflows (corridors, cross-sections, track design) and rendering policy stay out of it and belong to the application that composes it.
