General Settings

By selecting Modify Setup, the settings for the In-Session Setup can be altered, or a new Setup can be created.

NOTE: It is not possible to edit the predefined setups in <> brackets!

IFC Version allows the selection of the IFC version and MVD, typically IFC2x3 Coordination View 2.0 or IFC4 Reference View. For a better understanding of the IFC Version and MVD, check the first chapter of this manual.

Exchange requirement is only valid when using IFC4, as buildingSMART has defined different use cases for the certification of Architectural, Structural, and MEP exchange. However, the resulting differences in the exported IFC are minor and negligible for most end users. Structure or MEP is recommended for any trade-specific use cases and calculations. For general data exchange, please use Architectural.

Category Mapping (New since Revit 2025) For more information, please check this section.

File Type allows the selection of alternative types such as IFCXML or the zipped versions of IFC / IFCXML. For most use cases, the default setting IFC should be your first choice.

Phase to export allows the selection of a specific phase in the project to be exported. The default phase to export is the last phase in the project. If „Export only elements visible in view“ (available in Additional Content) is selected, the phase of the current view will be used, and this option will be greyed out. When exporting Phases, only existing elements will be exported - if an element is shown as demolished in the phase selected for export, the element won't be exported to IFC. This won't apply for Revit Links, resulting in demolished elements from a linked file being exported.

Space boundaries defines the level of room/space boundaries exported:

- None - room/space boundaries are not exported.

- 1st level - the room/space boundaries are included but are not optimized to split elements with respect to spaces on the opposite side of the boundary.

- 2nd level - the room/space boundaries are included and are split with respect to spaces on the opposite side of the boundary. A second-level space boundary considers the material of the building element and the adjacent spaces behind it, providing thermal properties for further analysis.

The information is attached to spaces as well as to room boundary objects like walls and can be viewed by most viewers (example FZK viewer, left Level None, right 1st Level):

Split Walls, Columns, Ducts by level splits all elements crossing multiple building stories automatically when exporting. When using this option, it is important to check levels defined as Building Story and also review the option Level Above. .Default will use the next higher Building Storey to cut all elements assigned to the current level, unless another level is selected explicitly. The elements created by splitting will be assigned to the levels they were cut by.

File Header Information allows the definition of Author’s name, E-Mail, Organization and Authorization in the file IFC header.

Project Address overwrites the address set in the project information either for building and/or site when exporting and also pushes this information back to Revit if Update Project information is selected.
