Save a model as an IFC file for use with an IFC-certified application that does not use the RVT file format.
The <In-Session Setup> option is a modifiable setup which is not saved between sessions. You can configure the options as desired to export the model to IFC. There are 9 built-in setups. These setups correspond to the IFC version options. These setups cannot be modified or deleted, but they can be duplicated to customize the IFC setup.
