IFC Exports from Revit

Industry foundation class, or IFC files, have long been a way to exchange 3-D model geometry with information between platforms. The majority of usage for me has been in the steel industry or exchanging Revit files with applications such as ArchiCAD.  Revit has included the ability to export IFC files like many of the Autodesk applications for some time now, however, they enhanced it a short time ago to add additional capability for managing the categories and different options of exporting our data.

A normal approach in Revit for exporting files is to set up individual 3-D views with that specific name in mind, i.e., 3D Navisworks, 3D Glue, 3D IFC, etc., and configure the visibility for categories that you do or do not want to export.  This typical workflow of setting up a 3-D view for specific export format is often handled by being able to accept a check box for “Current view only” in the export dialog.

This controls export of desired items that are visible in the view.  But with the new user interface enhancements (loaded enhancement from Autodesk Exchange Apps)  Autodesk embeds in recent versions of Revit, this check box no longer exists in the standard export dialog. We now do this by selecting the Modify Setup button and see that there are many pre-configured export setups that we can use along with additional check box items to tell Revit what we want to export.

 The “Export only elements visible in view” check box is now located on this dialog that we must configure before actually performing the export in the normal dialog.

Standard installs of Revit without the enhancement from Autodesk Exchange Apps will still see the older dialog version, but if you wish to utilize the additional features in images shown here, go to https://apps.exchange.autodesk.com/en and login per your Subsciption credentials and download the IFC 2015 – or IFC 2016, already posted.
