IFC4x3 linear positioning: alignments, referents, linear placement, spirals.
Documentation

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.

cargo add ifc-alignment

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.
