Import an IFC file to a combining job
You can import IFC files to the Combining module to be used for a preliminary list or for advance bills of materials.
As a comparison to Microsoft Excel worksheets, or KISS files, using IFC files allows revised items to be updated, and you can report the changes (material size, quantity, and so on) during the import process.
We recommend that you use the Steel fabrication view or 2x3 EM11 IFC format, but the Coordination view or the standard IFC2x3 format works as well.
Before you start importing, ensure that you have created preliminary marks (PRELIM_MARK) in Tekla Structures, and included those in the IFC files. In Tekla PowerFab, map at a minimum the PRELIM_MARK to Reference Number. Other mapping is optional.
If you import the IFC file to the same job, you can use the Add & Replace option.
If you have changed some fields in some of the records in the job, such as quantities or grades, the import reverts the changes made in the job, and the Import log shows that a number of items were updated.
