Exporting ifc files from Revit
The Revit IFC plugin
The open source ifc plugin developed by Autodesk adds a lot of extra options to the default ifc exporter dialog. If you want to export an ifc files from Revit it’s highly recommended to install this plugin.
There are two versions of this plugin, one is available from the Revit Store, the other is downloadable from Sourceforge. You have to install a separate plugin for every Revit version.
The sourceforge and store version signed differently, so they are not compatible to each other. My experience is that the sourceforge version is somewhat more “stable” than the store version. I mean, the store version can stop working after Revit and other updates. This claim needs more testing.
You can download them from here:
Exporting parameters
Fortunately this is very well documented in the help:
Go to Export Ifc>Modify Setup>Property sets
- Export Revit property sets: it will export all Revit properties of all elements to ifc
- Export user defined property sets: it will export only selected Revit properties to a custom property set, more info and example config here: Official help
- Export parameter mapping table: You can select revit properties to export as standard ifc properties, more info and example config here: Official help
