IFC Syntax : Geometry Profiles
A profile is the 2D cross-section that an IFC swept solid moves through space to
produce a 3D shape. Walls, slabs, beams, columns, footings, and pipes are nearly all
modelled as a profile plus a sweep. This skill covers the profile entities, the
required-versus-optional attributes, the WHERE rules they must satisfy, and the
IFC2x3 / IFC4 / IFC4.3 version differences.
Applies to IFC2x3, IFC4, and IFC4.3. A few attributes and subtypes changed across versions : see the Version Differences section.
A profile carries the shape only; the sweep that turns it into a solid is covered by
ifc-syntax-geometry-swept-solid.
