[in] An initial schema name to be used for the new instance creation.
Returns
A smart pointer to the OdIfcFile object that represents the created database instance.
Remarks
If the parameter string is empty, the created .ifc file doesn't have underlying OdDAI::Model object. This way of initialization is used for the file open operation when the underlying model should be created during the file loading process. The host application services object is associated with the newly created database.
