IFC 2017

Autodesk, Inc.

Digitally signed app




The IFC for Autodesk® Revit® 2017 contains up-to-date improvements on the default IFC import and export capabilities of Revit contributed by Autodesk and our Open Source contributors. 


While this app is not necessary for IFC support, it is recommended that users that depend on the quality of their IFC files download this app and keep it up-to-date, as new enhancements and defect fixes are added, for more information on IFC, please visit the building SMART website ( http://buildingsmart.org) or the Revit wiki (http://help.autodesk.com/view/RVT/2017/ENU/?guid=GUID-6708CFD6-0AD7-461F-ADE8-6527423EC895).

Версия, 12.04.2017
General: - Minor improvements to the Importer class to make it easier for developers to create a custom Importer. - We now support the IFC4 Addendum 2 schema. Specific improvements based on that will be listed below. For this update, you will have to manually add the IFC4_Add2.exp file (downloadable from http://www.buildingsmart-tech.org/ifc/IFC4/Add2/IFC4_ADD2.exp), to the EDM subfolder of your Revit Program folder. We will automate this in a future update. New Export Functionality: - Allow overriding material names on export by using IfcName shared parameter. - Expand the use of types for many elements that didn't export types before, including beams (IfcBeamType), curtain walls (IfcCurtainWallType, and types for mullions and panels), and footings (IfcFootingType). - Improved ability to export some geometry as IfcSweptSolid. - Try to use axis information, if it exists, when exporting beams and members in addition to columns. - (IFC4) Better support beam, column, and member base quantities, including weight. - (IFC4) Collect material information for profiles for beams and columns. - (IFC4) Expand use of FootPrint representations to columns and slabs. - (IFC4) Expand use of IfcMaterialLayerSetUsage if the entity has a compound structure in Revit, as allowed by IFC. - (IFC4) No longer create StandardCase IFC entities, as these have been deprecated (including IfcWallStandardCase). - (IFC4) Support IfcMaterialConstituent and IfcMaterialProfileSet for a number of elements. - (IFC4) Use Built-in parameter "Structural_Bend_Dir_Angle" to get "Roll" property for PSet_BeamCommon and PSet_ColumnCommon. - (IFCAdd2) Support IfcPolygonalFaceSet. Export Bug Fixes: - Allow exporting to IFC while using Collaboration for Revit where the default directory isn't local. - Better support for MEP type entities, that didn't always export correctly. - Correct the parameters of the directrix of some IfcSweptSolids. - Fix correct mapping of IfcBurnerType/IfcGasTerminalType and IfcElectricHeaterType/IfcSpaceHeaterType. - Fix creation of types for sub-entities of IfcDistributionControlElement. - Fix offset problem when using the "Export Linked Files as Separate IFCs" option in locales where the decimal mark is not a point. - (IFC4) Correct names of IFC4 entity quantity sets. - (IFC4) Fix the name of IfcCommunicationsApplianceType. New Import Functionality: - Add support for IfcDerivedProfileDef. - Support IfcRelClassification. - (IFC4) Support IfcMaterialProfile, IfcMaterialProfileSet, and IfcMaterialProfileSetUsage. - (IFC4) Support IfcMaterialConstituent and IfcMaterialConstituentSet. - (IFC4) Support IfcTessellatedFaceSet and IfcPolygonalFaceSet. - (IFC4) Improve mapping from Roll parameter to structural bend direction angle. - (API only) Allow for two new options, CreateDuplicateZoneGeometry and CreateDuplicateContainerGeometry, that disable the duplication of geometry for zone elements and containers, respectively. Import Bug Fixes: - Better reporting when importing an IFC file with invalid rectangular or circular profiles (e.g., a 0 radius profile). - Don't show the void geometry when subtracting a void from an empty solid as a result of an IfcBooleanResult calculation. - Ensure that IFC2x schema files can still be imported. - Fix import of some IfcSurfaceCurveSweptAreaSolids.

  • IFC solid export when overlapping
    Iván Pajares | июня 09, 2017

    Solid volumes representing door opening sweeps get exported as either the correct solid or it's negative representation. ie: a 90 degree sweep gets exported as a 270 degree sweep. It seems to relate to whether the solid in question overlaps or clashes with the rest of the door geometry...

    Hi, please send a sample file with more detail to revit.apps@autodesk.com and we'll take a look.

    Angel, I sent you the rvt and ifc test model. Regards

  • IFC Import
    Keith Wilkinson | апреля 18, 2017 Проверенная загрузка (Что это такое?)

    Hi, are there any plans to allow an IFC to utilise Revit's project coordinate origin rather than it's geometric origin to help deal with the issues of importing IFC's generated from packages such as Archicad?

  • Curtain walls. True North
    Lauri Suuronen | апреля 13, 2017 Проверенная загрузка (Что это такое?)

    Curtain walls need to export with curtain walls nested as panels. There also needs to be an option to export with Project North orientation. Currently, we cannot make use of Revit's True North orientation in projects with multiple buildings sharing a common project origin, or in projects where the project origin is a geographically fixed point in the first place.

  • Loading IFC4_Add2.exp

    Angel, Any tips on how to activate the file after it is placed in the EDM folder? Thanks Scott

  • Export IFC local coords
    Remy Maurcot | марта 01, 2017

    It would be really interesting to have an option to export in local coordinate.

    Miquel Rodríguez | марта 25, 2017

    If you define two Sites in the Manage(TAB)-Location (Project Location) command, and one has the survey point at 0,0 with no north angle rotation, and the other with the correct Geolocalization, you can set to current one of them and the IFC will be oriented with the local or the global coordinates.

  • IFC link ceiling problems
    Lars Johansson | февраля 16, 2017 Проверенная загрузка (Что это такое?)

    Having some problems when linking an IFC file into Revit, the ceiling is placed in a wrong height. I have created the model in Revit, used the extended IFC exporter, when I open the IFC file in e.g. Solibri the ceiling is placed correct. If I try to open the IFC file directly in Revit, the ceiling is placed correct, but if I use link IFC, into Revit the ceiling is “moved” down.
