Navigate to https://iTwin.bentley.com
Select your iTwin if you don’t see the iModel you want to export to IFC.
Once you have your iModel, you have two choices for where you can initiate IFC Exports.
Once you see the iModel you want to export, click on the three dots. Select the Export to IFC menu item.
This brings up the Export to IFC dialogue.
Toggle the "Filter based on Saved View" to create the IFC export based not on the entire iModel, but based on one of the saved views defined in Design Review. This can result in a much smaller IFC file which can be particularly useful on very large models.
Alternatively, Exports can be triggered from any saved view. First bring up the Saved Views dialogue and click on the ... of an individual view. This brings up the following view:
Select Export.
In this case, there is no selection of views as the export will be based on the saved view that was selected to bring up the export menu.
You can also optionally pick to have the log files copied to the same location as the generated IFC file by toggling "Save Logs"
Select the IFC format. Currently supported formats are IFC 4.3 RC1, IFC 2X3, IFC4 RV 1.2 and IFC 2X3 CV 2.0.
Optionally, you can select a custom mapping file to be used for the IFC Export. A base mapping file can be found here:
Schema mapping
Once you click on Export, a message will appear near the top of the window:
You will receive an email once the IFC file has been generated. Go to the Project Share and download the file.
