A brief history of Interoperability at erability1996Autodesk isFoundingMemberof the AIA*20112016AutodeskintroducesRevit IFC asopen sourceIFC-Supportfor Inventor*International Alliance for Interoperability, 2008 renamed to buildingSMART20182020Autodesk releases thefirst Revit IFC manualin English, German,French and SpanishIFC 4 certification forRevitAutodesk becomes amember of OpenDesign Alliance (ODA)and joins thebuildingSMARTStrategic AdvisoryCouncil

Autodesk IFC Viewers
Autodesk Navisworks Simulate / Manage Can read many common formats, including IFC Additional capabilities like filtering, comments,markups, 4D/5D etc. The Navisworks IFC reader is updated togetherwith the Revit IFC Plugin (apps.autodesk.com) Important: Navisworks has two conversionmethods for IFC:o Modern: uses the Revit IFC engine, default settingo Legacy: older Navisworks engine, can be faster withlarge non-Revit IFCs

IFC Workflows onCloud
Uploading IFC Files1. Upload through the browser2. Upload through the Desktop Connector
IFC files as part of the Design Collaborationprocess
IFC Files in Model CoordinationCurrently supports IFC files exported from ARCHICAD, Revit, MagiCAD for Revit and Tekla Structures
Exporting Revit File toIFC
IFC export stepsSTEP 1: Load the IFC mapping file that youwant to use to export to IFC.STEP 2: Select Export (IFC).STEP 3: Navigate to the target folder for the IFCfile.STEP 4: Select the IFC setup to use to generatethe fileSTEP 5: Enter a name for the IFC file and selectexport
IFC Best Practices
IFC Best Practices:1. Setup options for IFC import/export
Link vs OpenLink IFCOpen IFC Intended use as a reference for coordination Imports the content of the IFC file in Revit Best results / main development focus Converts elements to native Revit geometry No editing of the IFC file possible Can lead to data loss / errors
Settings for linking / opening IFC files Use a minimal template(no preloaded families,views etc.) Standard mappingshould be working formost use-cases, can beedited if needed The quality / correctclassification of theexported file isessential – only fewthings can be tunedafter the export
Exporting IFC Files from Revit – global mapping Standard mapping should beworking for most use-cases,can be edited if needed Focus on classes for RevitCategories (support for RevitSubcategories / IFC Types islimited on global level) Reset the hardcodedsettings by deleting thestandard file and thenselecting Standard
Class Mapping on element level - IfcExportAsParameter can be added on instance or type level, recommended to use a shared parameterNotExportedExample:Floor covering in Revit as a separate slab – override the standard export to IfcSlab by using IfcCovering.FLOORING
Navigating the buildingSMART documentation
Levels in IFCOnly Levels which are marked as “Building Story” are exported
IFC Best Practices:2. Always use the common IFC properties first3. Only if there is no common property,create own property sets
What are Common property sets?
Properties export settingsBig and cluttered filesPart of IFC schema, keep onPart of IFC schema, relevantfor QTO
Common property default mapping Example: Pset WallCommonIFC PROPERTYREVIT PROPERTY (Built-In)ReferenceComponent type (type name)FireRatingFire-resistance class (type property)ThermalTransmittance U-value (type property)IsExternalExterior component (type property)LoadBearingLoad-bearing (instance property)ExtendToStructureTop is attached (instance property)Acoustic ation-Properties already part of the defaultRevit Database are mapped automaticallyWhere no default Revit properties exist:- Revit properties with the samenaming and data type will bemapped automaticallyOR- Use parameter mapping table tomap other properties
Common property default mappingBuilt-In Parameters
Common property default mappingAdditional common parameters added to project (same naming as in IFC documentation)
Common property custom mappingMaps Revit Parameter to Standardparameters defined in the IFCschema according to a definition ina .txt file (UTF-8 encoding)Schema:IFC Common PropertySet Name tab IFC Property Name tab Revit Property NameSample Result:Pset WallCommon Combustible CustomParameter1
Creating custom property sets
Creating custom property sets with schedules Create a schedule with the desired parameters Schedule Name Property Set Name Preferable add IFC, Pset or Common in the title toavoid exporting all schedules to property sets
Creating custom property sets with a mappingfile Define properties in a .txtfile (UTF-8 encoding) –template including Much more flexileapproach and themapping file is storedoutside of the Revitproject and can be easilyshared
Name of your PsetProperty Name in IFCSample ResultInstance or typeData typeIFC classes, separeted by ,or IfcBuildingElement for allclassesOptional: Revit property nameif different from desired IFCname
IFC Best Practices:4. Large models may need to be exported insections.5. Only export what you need – Data andgeometry
Visibility options Use Worksets to control visibilities and ‘Export only elements visible in view’
Check for completeness Open the export in an IFC Viewer
IFC Best Practices:6. Ensure your machine has enough RAM7. Document process, and settings within BEP8. Report issues to eshttps://knowledge.autodesk.com/contact-support

3 6. Open the Autodesk Revit project in which the IFC file should be imported. In the Add-Ins menu, you can choose to import the REMAK IFC file (1), or you can add the option to the Quick Access toolbar (2) 7. If you want to import the REMAK IFC file, click on the Remak import IFC option (1), then the system dialog opens.
