We've got different IFC files with a lot culverts in them. Different types come in different files. They are spread over a wide area. We try to export the IFC data for a specific small area, means the data we'd like to export into one file could originate from different files.
We have to select the IFC objects anyway, so why do we have to specify the file it came from as well. TBC can get this information from the selected object itself.
And we can only select one single origin file. Means, we can't combine IFC data from different origins into one single new file.
