Print Wall Properties
The PRINT WALL PROPERTIES sample program prints the properties associated with each wall instance in an IFC file. It iterates over all IfcWall instances in a file, then searches for the property set definitions related to each. Then it prints the properties in each property set. The C++ version of the program demonstrates how to use backpointers to efficiently find the relationship objects that refer to each wall. Use this as the starting point for a more sophisticated program.
