XS_USE_INTEGRATED_BUILDING_HIERARCHIES
Category in Advanced options dialog: Modeling properties
To define a building
hierarchy structure in the Building hierarchy side pane, set this advanced option to TRUE. The
default value is TRUE.
The building hierarchy structure is also shown in Organizer, and it is used in IFC export.
If you want to use Organizer or user-defined attributes to define the hierarchy, set the
advanced option to FALSE, save the
model and reopen it to apply the change. When the advanced option is
set to FALSE, IFC export uses the
hierarchy defined in Organizer or with user-defined attributes.
This advanced option is model specific and the setting is saved in the options database.
Reopen the model after changing the value to activate the new setting.
