Model Filter for IFC Export

File > Interoperability > IFC > IFC Translators

Choose a Translator for Export and open the Model Filter preset.

Select 3D Elements to Export

This filter defines which Archicad 3D elements should be exported to IFC. You can filter by the elements’ Structural Function and/or by their IFC Domain.

•By Structural Function

This is an additional filter to the IFC Domain filter set below.

-This filter considers the Archicad element’s “Structural Function” category: Either Load-Bearing or Non-Load Bearing. This is set for each element in its Classification and Properties panel of Element Settings.

- “Load-Bearing elements only” means that only those elements classified as “Load-Bearing Element” (plus Archicad Zones) will be exported from Archicad to IFC.

•By IFC Domain

Note: An element’s IFC Domain depends on its Type Mapping preset.

–“All” includes all elements from the model

–“Structural” includes only the structural building elements

–“MEP” includes only the mechanical elements (IfcDistributionElement).

See the exact composition of each Domain filter in the tree list below. Modifying this filter will create a “Custom” filter.

Select 2D Elements to Export

•Grid System and Elements: Check this to include the Grid Elements and the grid members of Grid Systems in the exported file.

Grid elements will show up in the IFC structure as IfcGrid.

•Lines, Texts, Labels, Fills: Check this to export these 2D elements, plus all dimension types.

–2D elements will show up in the IFC structure as IfcAnnotation.

–Dimensions will be exploded into lines and texts, since the IFC2x3 standard documentation does not include a dimension element.

–The inclusion of 2D elements in the exported file is also affected by the “Elements to Export” filter at “IFC Save Options”: if a 3D view is currently active, the 2D elements can be included only if the “Entire project” option is selected in that filter. (See Filter Model at Export.)

–IFC4 Reference View does not allow annotations. To ensure compatibility for IFC4 Reference View, leave this box unchecked.

•Door/Window 2D Views: Check this box to include the 2D symbols of doors and windows in the export process, in addition to 3D model geometry. This is handy if the recipient program recognizes these data and can correctly display, for example, the door opening directions.
