Class TIfcFile

Unit

CastleIfc

Declaration

type TIfcFile = class(TIfcPersistent)

Description

IFC file representation.

This class is not defined in the IFC standard, but it is consistent with how the IFC file is actually represented, in both STEP and JSON encodings. The file starts with some metadata (in STEP header, on JSON top-level object) and then follows the "data" which is TIfcProject instance.
