Enhanced Workflow: IFC Model Exchange with ArchiCAD for Revit

What it Does

IFC Model Exchange with Archicad Add-In has three functions:

‣

“Improved IFC Import” imports IFC models to Revit using extra features that improve the interpretation of architectural models;

The Improved IFC Import command of the IFC Model Exchange with Archicad Add-In is recommended for IFC import of architectural models to Revit applications - especially in case of model exchange with Graphisoft Archicad - and has the following main functions:

‣

Direct import of IFC2x3 (.ifc and .ifczip) files

‣

Extra import improvements

Set Project Information using IFC Project data: The main parameters of the Project Properties dialog (Manage > Project Information) are set by mapping the IFC Project data of the IFC model.
Correction of True North settings: Revit “True North” data is set by using the North direction of the IFC model. Note: It is recommended to use a common anchor/reference point to facilitate coordination of models from different programs. To define this reference point, use Survey Point. Both Archicad (from version 20) and Revit provide a function to define Survey Point.
Conversion of Structural Floor elements: Load-bearing IFC Slabs are converted to Revit Structural-type Floor elements.
Improved import of IFC Spaces: IFC Spaces (Archicad Zones) are converted to Revit Room elements by placing them at their correct locations. Rooms are created from the footprint of the IFC Spaces, inner holes are considered in Room generation, and Room tags are displayed correctly.
Mapping of Archicad Renovation Status to Revit Phasing: Archicad “Renovation Status” is converted to Revit “Phasing” data. Phase mapping takes place based on the current Revit template’s first and last project phase, as defined in IFC Options (Open menu). Example: With the “Architectural” (default.rte) template, the imported Archicad “Renovation Statuses” are mapped as “Existing” and “New Construction” phases. Thus, all imported Views are assigned a “Phase Filter” that displays elements having a “New” or “Existing” status (and hides elements having a “Demolished” status).
Override the Detail Level and Visual Style of the template Views: This function sets “Fine” Detail Level and “Consistent Colors” Visual Style for all Views defined in the template which the IFC import is applied for. It also creates a default 3D View (if not available in the template) with the “Fine” Detail Level and “Consistent Colors” Visual Style display settings.
Import of all IFC parameters as schedulable Revit parameters (optional): This function imports all Attributes, Properties and Classification Reference data of the IFC model elements as schedulable Revit parameters in the group called “IFC Parameters”. A Property name is shown together with its container “Property Set” name in brackets. The value of a Classification Reference parameter consists of its “Item Reference” and/or the “Name” component. Unicode file encoding is fully supported by property value import. IFC Model Exchange with Archicad for Revit 2025 5 Improved IFC Import IFC Model Exchange with Archicad for Revit 2025
Auto-Join Elements (optional): This function joins Walls automatically to other Walls or to Columns. For more control over the import results, try disabling this function.
Correct lines that are slightly off axis (optional): If you enable this option, lines that are slightly off-axis will snap to the nearest axis. This may eliminate some warning messages but may also modify the shape of sketch-based elements and extrusions. To retain the original geometry, leave this option disabled.

The steps of the improved architectural model import:

In Revit, go to the IFC Model Exchange with Archicad panel on the Add-Ins ribbon and click the Improved IFC Import command. Note: The “Improved IFC Import” function uses the settings of Revit’s IFC Options (Open menu). Revit generates “Generic Model” category elements from some special IFC entity types. For example, an IfcFlowController or an IfcCovering element is converted to Generic Model element by default. If you want to manage the target Revit category type for the imported model elements by IFC entity type, you should modify and save the mapping rule before using the Improved IFC Import command. The mapping of Archicad “Renovation Status” to Revit “Phasing” is also done based on the template’s phasing settings (if any) defined at IFC Options (see above).
In the open dialog box, select the IFC(2x3) file you would like to import.
The Add-In imports the IFC model with corrections and improvements.
After finishing the IFC model import, a dialog box summarizes the results of the improved import processes.

“Link IFC” merges IFC models into the current Revit project as a non-editable reference;
“Export to Archicad” exports Revit model elements in IFC files that are specially enhanced for use in Graphisoft Archicad.
