Description

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).

About This Version

Version 17.4.0.0, 7/19/2017
General: •Added extra UI and functionality to make COBie IFC exports easier. Specific improvements will be detailed below. •TODO: Some of the new fields will be localized to French in a future release. New Export Functionality: •Allow curtain wall mullions to export as any supported IFC entity. •Allow families to export as IfcPile with corresponding IfcPileType. •Improve export of axis representations for structural elements. •(COBie) Add COBie Company Information tab in Modify Setup if COBie export is chosen. •(COBie) Add COBie Project Information tab in Modify Setup if COBie export is chosen. •(COBie) Improve entity naming for COBie export. •(COBie) Rename "IFC2x3 Extended FM Handover View" to "IFC2x3 COBie 2.4 Design Deliverable" •(IFC4) Improve export of material layers. •(IFC4) Modify Setup has an option to force triangulation only for tessellated outputs. 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. Import Bug Fixes: •Improve heuristic that decides the "best" material to export when we can only assign one material to geometry. •Stabilize GUIDs of some IfcOpeningElements. •Stabilize order of creation of geometry with multiple clippings and openings, to have consistent output.

  • IFC doesn't open in Navisworks
    Toivo Moustgaard | August 24, 2017 Verified Download (What's this?)

    IFC files exported with IFC 2017 versions 17.3.0.0 or 17.4.0.0 don't open in Navisworks. Where can I get older versions?


  • Export linked files as separate IFCs
    Øyvind Seime | July 13, 2017

    When running "Export linked files as separate IFCs" I get an IFC of the complete linked model. Is there a possibility combine this with "only visible in view"?


    Andy P | August 08, 2017

    That should be possible - we just haven't done it yet. I will make an item to get it done.


  • IFC solid export when overlapping
    Iván Pajares | June 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...


    Angel Velez (Publisher) | June 12, 2017

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


    Iván Pajares | June 15, 2017

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


  • IFC Import
    Keith Wilkinson | April 18, 2017 Verified Download (What's this?)

    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 | April 13, 2017 Verified Download (What's this?)

    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
    Scott Beazley | April 12, 2017 Verified Download (What's this?)

    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 | March 01, 2017

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


    Miquel Rodríguez | March 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 | February 16, 2017 Verified Download (What's this?)

    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.
