如果上述方法不完全适用于附加楼层和内部楼层,则 levels can be added manually in the 楼层管理 window based on the data of Ifc楼板 and Ifc屋顶 taken from the 参数表. 更多信息,见: Create additional and internal storey levels.
After interpreting an Ifc楼板 element for the main storeys that does not match existing levels elevations, create an internal level based on the storey ordinate with the command 创建内部楼层 from the right click menu.
To simplify the handling of multiple storey levels, the function 显示楼层标高 can be used. The elevations are taken from the data defined in the 楼层管理 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.
