The article describes the way of creating a building structure with additional and internal storey levels based on the IFC model.

Examples of use
Preparation of complete building structure with additional and internal levels interpreted from the IFC model
There are several paths to create additional and internal storey levels:
Choose the Slab and the Roof that define the elevation of the additional level and select the function Create an additional storey level between the selected slabs/roofs from the IFC file;
If the above method is not entirely suitable the additional and internal levels can be added manually in the Storeys management window based on the data of IfcSlab and IfcRoof taken from the Data table. For more information, see: Create additional and internal storey levels.
After interpreting an IfcSlab element for the main storeys that does not match existing levels elevations, create an internal level based on the storey ordinate with the command Create internal storey level from the right click menu.
To simplify the handling of multiple storey levels, the function Storey levels visibility can be used. The elevations are taken from the data defined in the Storeys management window.
Executing the IFC export
By default the program does not separate additional and internal levels during exporting. The levels are exported on the same sheet together with the corresponding main storey.
