IFC 2x3 -- Industry Foundation Classes

Sample Programs

Create an IFC building with a simple block shape in C++ and Java. Also makes GUIDs, owner history, units, and basic spatial structure.

HELLO WALL

The HELLO WALL sample program creates a standard wall and attaches property sets and quantities to it.

PRINT SPATIAL

Recursively print the spatial structure defined in an IFC file, beginning with the IfcProject root.

PRINT WALL PROPS

Find and print the properties associated with each IfcWall instance in an IFC file.

Overview

EXPRESS source and associated files for IFC 2.x3 TC1 protocol, developed by the International Alliance for Interoperability, now called buildingSMART. You can also find more information on the older older IFC 2x2 and newer IFC4 models.

Programming Libraries

For C++ programming, the ifc2x3lib class library is pre-installed and provides IFC-specific classes for use with the ST-Developer ROSE programming library

Include File: ifc2x3.h
Include Path: $(ROSE_INCLUDE)/ifc2x3lib
Library Path: $(ROSE_LIB) with ifc2x3lib.lib or -lifc2x3lib
Class List
How to use

For Java programming, the ifc2x3lib jar file is pre-installed and provides IFC-specific classes for use with the ST-Developer Java programming library. The "-preservecase" option is used when generating the library, so class names and access functions have the same "CamelCase" capitalization as the IFC EXPRESS.
