Initialize and Deinitialize IFC SDK

As usual for ODA products, before starting to use IFC SDK functionality, you need to initialize it. To initialize IFC SDK, use the odIfcInitialize(); function which is declared in the Include/IfcCore.h header file. This function loads the appropriate modules that provide IFC SDK functionality. It accepts two parameters:

bInitIfcGeomResource — A flag that determines whether geometry functionality should be initialized as well. This flag is required for working with geometry objects.
modelerType — Determines which type of geometry is supported. By default, facet geometry is supported.

Before calling the odIfcInitialize(); function, sequentially call the odrxInitialize() function to get access to Rx-functionality and the odDbRootInitialize() function to initialize drawing database functionality:


odrxInitialize(&svcs);
odDbRootInitialize();

odIfcInitialize(true);

To clear up the environment before finishing an IFC SDK based application, call the odIfcUninitialize() function. If you called the odrxInitialize() and/or the odDbRootInitialize() function previously, don't forget to call the odrxUninitialize() and/or odDbRootUninitialize() functions. Note that you have to keep the calling sequence when de-initializing IFC functionality:


odIfcUninitialize();

odDbRootUninitialize();
odrxUninitialize();
