IfcAlignmentTransformEnum

Semantic definitions at the type

Type definition

Indicates how an element may be transformed when placed along an alignment.

Enumeration definition

Constant	Description
PLACE	Element is placed such that the local position corresponds to the point along the referenced curve, such that any components retain their relative cartesian positions and no geometry is transformed.
CHAIN	Element is placed at the global origin, and geometry at the element and components is transformed by mapped item corresponding to the point along the referenced curve.
WARP	Same behavior as CHAIN, except any axis-driven parametric geometry (having an 'Axis' representation) is transformed to follow the alignment curve.
