Description

The IFC for Autodesk® Revit® 2016 contains up-to-date improvements on the default IFC import and export capabilities of Revit contributed by Autodesk and our Open Source contributors. This app also includes an alternate UI for the export that has extra options from the default.

 

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/2016/ENU/?guid=GUID-6708CFD6-0AD7-461F-ADE8-6527423EC895).

A propos de cette version

Version 16.6.0, 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.

  • More options but where can I find a manual?
    Marcus Isacsson | août 14, 2017 Téléchargement vérifié (Qu'est-ce que c'est?)

    Hi! This sure improves IFC exports. But I wonder, where can I find a manual or description explaining all the different options and their effect on the export?


    Angel Velez (Editeur) | août 24, 2017

    We need to compile a proper manual. Resources are available in the help, in the help HTML document included with the installer, and also in the Revit IFC SourceForge website.

  • export IFCBUILDING parameters
    坤睿 郭 | mars 10, 2017

    Can this software export IFCBUILDING parameters defined by myself?


    Angel Velez (Editeur) | mars 13, 2017

    Hi, you can set BuildingDescription and BuildingLongName in the Project Information and these will be exported to IFC. Other parameters added in Project Information should also be associated to the building, including PSet_BuildingCommon, and internal Revit property sets, if those are being exported with the file (by default, Revit property sets are not exported; you'll have to go to Modify Setup and the Property Sets tab to add them).


    坤睿 郭 | mars 14, 2017

    Hi, Angel Velez, I got your meaning, but I want to export the parameters defined myself, such as BuildingCost (I defined that). I know that it is difficult to add one more (that is the key point) parameters to the "project parameters" in the Revit. So can it be done?


    坤睿 郭 | mars 14, 2017

    OK, after some trying, I solve it by rewriting the .ifc file directly. And there is another question, what is the writing code of Chinese words? The name of some parameters is Chinese


    Angel Velez (Editeur) | mars 15, 2017

    There is information on how to write Unicode parameters into an IFC file here: http://www.buildingsmart-tech.org/implementation/get-started/string-encoding. Also, you should be able to add a shared parameter to "Project Information", and that will export to IFC with the IfcBuilding property sets. Hope that helps.


    坤睿 郭 | mars 20, 2017

    Yep! I solve my question! completely! thanks a lot!


    Rasa Zukauskaite | mai 16, 2017

    Hi, maybe you could write all steps how did you solve your problems with parameters? I really appreciate that. I am trying to place Level parameter at Curtain Panels defined by myself, but when I make an IFC export I lost all parameters which I created....


    坤睿 郭 | mai 17, 2017

    Hi, Rasa Zukauskaite, by rewriting the .IFC file you can do some simplify extending. But, as I know, there some parameters can not be extended.


  • Ifcbuilding Parameters
    坤睿 郭 | mars 10, 2017

    After some exercise, I found that if I export "ifcbeam","ifc column" parameters (defined by myself), this software works well. But if I want to export "ifcbuilding" parameters (defined by myself), it always failed. So my question is: Is this software can export parameters defind by myself for IFCBUILDING?

  • Losing IFC Geometries
    Travis Willson | décembre 19, 2016 Téléchargement vérifié (Qu'est-ce que c'est?)

    I am working with Revit, Navisworks and Tekla and am experiencing some issues. I am receiving an .IFC model from a PEMB supplier that is exported from Tekla. I am then importing that file into my Revit model, which is working fine. I then am exporting my Revit file (including the PEMB file) back out to .IFC for use in a Navisworks model. During this last export from Revit to IFC, I am losing some of the PEMB geometries. All of the vertical structure and the mainframes are missing, but the other geometry looks great. Any ideas on how to fix this?


    Angel Velez (Editeur) | décembre 20, 2016

    Hi, the recommended workflow is that you don't re-export the linked in IFC file - just use the original IFC file for that. While I am sure that there are some improvements that can be made there, we will never be able to 100% reproduce the original content - just use that directly. That does mean that the receiving system needs to be able to receive two IFC files, but I think that's fairly common these days.


  • About IFC 2x4 standard
    vinoth prasath | décembre 08, 2016

    Is revit2017 fully support ifc 2x4 stanrard files ?


    Angel Velez (Editeur) | décembre 09, 2016

    We have IFC4 support, but we can't claim full support as of this writing because there is no certification process. We will continue to improve our IFC4 support and will look into participating in the certification process when it is available for the Reference View and Design Transfer View MVDs.


  • Revit & IFC
    Jelmer Eekman | novembre 24, 2016 Téléchargement vérifié (Qu'est-ce que c'est?)

    Numerous times i've seen walls completely disappear or malform in an export from Revit to IFC. This is completely unreliable and very risky to use as a communication toward manufacturers. Shame on you


    Angel Velez (Editeur) | novembre 25, 2016

    Hi Jelmer, I'm sorry you've had a negative experience with Revit and IFC. If you send us sample files where you see this bad behavior, we can examine them to see how to improve your process. Regards, Angel


  • Export only and grids
    W. Dantuma | novembre 11, 2016 Téléchargement vérifié (Qu'est-ce que c'est?)

    We use the "Export only elements visible in view" a lot. To have a good sense of what is being exported, we export from a 3D view. One of the disadvantages of this work method, is that grids are not exported, as far as we can tell. Is there a way, with the described method, to get the grids exported?


    Angel Velez (Editeur) | novembre 25, 2016

    Hi, there isn't an option to do this yet because the grids aren't visible in the view. We added the option to have rooms, so we can consider that also. Please add this request to http://www.autodesk.com/revitideas to see what the interest level is. Regards, Angel


  • IFC Export from MEP to SI units
    Jan Back | octobre 26, 2016 Téléchargement vérifié (Qu'est-ce que c'est?)

    Hello, When I export to IFC from Revit 2015 or Revit 2016 all flows for Air Terminals, duct, plumbing fixtures, pipes etc become in ft3/s (Cubic feet per second) in the IFC files. How do I change the IFC export so the units to be in liter per second or m3/s instead? I have project units i Revit project for HVAC Air Flow = L/s and for Piping Flow = L/s But when I export the Revit file to IFC the unit for flow change. I use the app IFC Export Alternative UI 16.5.0.0) in Revit 2016 and the app IFC Export Alternative UI 15.7.0.0) in Revit 2015 Best Regards / Jan Back


  • Link Revit to IFC
    Jimmy Chin | septembre 14, 2016 Téléchargement vérifié (Qu'est-ce que c'est?)

    Export Linked files as separate IFCs function is exporting linked files with incorrect phase filter to defined visible view. i.e. the linked file's exported ifc files has demolished elements exported where the visible view has 'show complete' as phase filter.


    Angel Velez (Editeur) | septembre 20, 2016

    Hi Jimmy, please send us some sample files at the revit.apps@autodesk.com email and we'll take a look.


  • Content not being exported
    Raymon Velthuis | septembre 02, 2016 Téléchargement vérifié (Qu'est-ce que c'est?)

    I've installed the new version 16.5.0. but some Generic Models were not exported at all. I've tested the same model on a different machine with the previous version installed and all worked fine. There seem to be some issues with the new version.


    Angel Velez (Editeur) | septembre 20, 2016

    Hi Raymon, we haven't heard this yet from other users, if you can send us a sample file we can take a look.


  • Can not export Layers to Custom set
    Cahit Okten | septembre 01, 2016

    I have a project which requires the elements to be exported to specific layers (Not to BS 1192). Choosing a different option does not seem to make any difference, it exports to BS 1192. Is this functionality not been implemented yet? I am using a workaround at the moment by naming the custom layer export settings to the standard BS1192.


    Andy P | octobre 13, 2016

    HI - You should be able to use the shared parameter "IFC CAD Layer" on elements to override the layer export. So you would create that shared parameter (it should be in the shared params file attached to this project under Misc), attach it to the project categories needed, and give it the value you want. Then the IFC file gets the proper IFCPRESENTATIONLAYERASSIGNMENT.


  • RVT - IFC - project north - project coordinates
    Line Rahbek | août 30, 2016 Téléchargement vérifié (Qu'est-ce que c'est?)

    Is it possible to export from revit 2016 to IFC format with project North and project coordinates instead of using true North and survey coordinates? This is giving us alot of issues., Thanks


    Angel Velez (Editeur) | septembre 20, 2016

    Hi Line, sorry at the moment those are the limitations. You can temporarily change project north and the survey coordinates before exporting. We are looking into providing options for a future release.


  • Export to IFC - Imperial Units?
    Clara Sandoval | juillet 29, 2016 Téléchargement vérifié (Qu'est-ce que c'est?)

    How does one do this? By default an exported IFC file is in centimeters according to Navisworks.


    Angel Velez (Editeur) | juillet 29, 2016

    By default, IFC will export the length units in whatever the display units are of the Revit file. Note that many viewers will also be able to change the display units, regardless of what units the file was exported in.


    Clara Sandoval | juillet 29, 2016

    In response to Angel: I want to produce an IFC file for my subcontractor scope that requires no manipulation in Navisworks to be in correct position relative to the rest of the building model. By default any IFC file I produce from Revit indicates "centimeters" when opening it later in Navisworks, and my scope is "way off in the broccoli" from rest of the building without adjusting "units & transform". I am in no way / shape / form using anything metric in Revit -- have used an Imperial template, and my project units under length category is decimal inches.


    Angel Velez (Editeur) | août 02, 2016

    Hi Clara, can you send us a sample Revit and IFC file to revit.apps@autodesk.com? We'll take a look, as the behavior you describe is not what we'd expect.


    Clara Sandoval | août 03, 2016

    I will prepare something to send to the email address you've provided. In the mean time, I've found steps that are working for me: http://whatrevitwants.blogspot.com/2014/05/when-and-how-to-neutralize-survey.html It seems the issue was not necessarily that my IFC exports from Revit insert into the Navisworks environment w/ model units as centimeter (I can live with this). My real issue was IFC exports were having my modeled geometry be not in correct relation to an externally-produced model for the whole building. This outside model, modeled in Revit, is what I utilized for my Revit model's project base point via shared coordinates. There seems to be no such option in the OOTB IFC exporter nor IFC 2016 add-in for adjusting the coordinate I need to utilize. You know how when you make an NWC export from Revit, there's an option w/in the Navisworks Options Editor so you can adjust coordinates to be Project Internal or Shared? This is what I believe is needed for exporting to IFC.


  • Lack of documentation means we don't know what we are exporting
    Luke O'Rafferty | juillet 25, 2016 Téléchargement vérifié (Qu'est-ce que c'est?)

    Results seem OK. Probably. But with 20 something options and no help text I don't really know what I am exporting. More tips built in please! I have seen a note about there being an HTML file somewhere, but it shouldn't be this difficult to work out what it is doing!


    Angel Velez (Editeur) | juillet 29, 2016

    Thanks for your feedback. There is an HTML help file in the directory where the add-in is installed, and there are two links above that take you to Revit help, and to SourceForge where you can ask more questions in the forum there. Note that if you want a standard export to the IFC format according to the most common buildingSMART MVD, all you have to do is press the export button - no other options are necessary.


  • Air Volume Flow Rate Inconsistency
    Alejandro Mata | juillet 21, 2016 Téléchargement vérifié (Qu'est-ce que c'est?)

    Hi guys, I'm writing this email because I would like to know if is possible why it doesn't export properly the air volume flow rate to ifc. I've tried revit 2015, 2016 and 2017 with the last version of the ifc export in all of them. For example, whit a volume flow rate of 235 l/s assigned to a duct segment gets exported to ifc as 8,29 m3/s which it doesn't make any sense. Any idea? Thanks in advanced


  • Hosted Walls
    Michael Coffey | juin 30, 2016 Téléchargement vérifié (Qu'est-ce que c'est?)

    Walls that are or were hosted to a mass by face do not show correctly.


    Angel Velez (Editeur) | juillet 07, 2016

    Hi Michael, Can you be more specific in your comment? Is this a problem on export, where the walls don't show correctly in another system, or is this a round-trip issue? Or is it something else entirely? Thanks, Angel


  • Export Room Information
    Yuki Sugita | mai 24, 2016

    Hi, I am wondering if there are any options to keep information for room.I set the outline for the room area inside exterior wall when I export as IFC.I would like to keep the boundary as INSIDE exterior wall but becuase of the default setting which is at the centre line of wall I have to change each room information as I import it....Hope you will help me.Thanks.


    Angel Velez (Editeur) | mai 24, 2016

    Hi Yuki, I may not fully understand the issue. IFC will use your room settings when creating space boundaries on export. Please email revit.apps@autodesk.com with more detailed information and we'll try to help.


  • Cannot import to TEKLA
    Ellen P. | mai 24, 2016

    Hi. I am using REVIT 2016 and I tried to export my model through this app as IFC 2x3. I tried to import it to TEKLA Structures 20.0 but nothing were imported. I tried other IFC versions but I still failed.I might be missing something. Please help. Thank you.


    Angel Velez (Editeur) | mai 24, 2016

    Hi Ellen, There are a couple of things to check. First, how big is the IFC file you are generating? If it is small (< 100 KB), then maybe there is an issue in creating the file. If it is large, then it may be a problem with Tekla. You can also try a third-party viewer, or using Link IFC in Revit, to see what you get visually when you try to read the file. The other thing to check is your export options. If all of your categories as set to "Not Exported", you'll get nothing in the file. Please email revit.apps@autodesk.com if you need more help.

  • Some simple changes will make a big difference
    Brian Renehan | avril 10, 2016

    First, well done on continuing to improve the IFC import and export. Some suggestions which will vastly improve our workflows and eliminate waste of time workarounds. On exporting and importing the IFC file, in the Dialogue box the user gets the option of the origin point, ie - Survey, Project or Hard-coded startup point. The current export to Survey base point is a big workflow problem for us at the moment. We don't want workarounds. Can you please provide detailed help on what each existing function in the export option does, and enable the user to save these settings out as an XML file for other projects. When exporting models with a large amount of FF&E the export is very slow and RAM intensive. My computer has 32 RAM and it maxes out on exporting a 160 MB model. Is the coding as efficient as possible? When exporting a shared Revit model, the export process locks out all outer users from the central file, is in many cases is causing their Revit Sessions to force a Recovery save. This needs to be looked at. Is it possible to enable a tool outside of Revit to automatically extract the Revit model to an IFC format. It would be great if this could be run out of hours. IFC will fast become to norm. We need tools around it that give Users the flexibility to make IFC work better to their project and workflows. Well done.


    Angel Velez (Editeur) | mai 03, 2016

    We appreciate all of your thoughtful feedback and will file or update IFC requests as appropriate. Regards, Angel


  • doesn't work either!! impossible to import a proper ifc
    Maria Mestres Domènech | avril 08, 2016 Téléchargement vérifié (Qu'est-ce que c'est?)

    The ifc shows perfectly in solibri and bimsight. WHY it doesn't do so when you open it in revit. Any idea of how to do it? This is so little BIM!!


    Angel Velez (Editeur) | avril 11, 2016

    Hi Maria, sorry that you are having trouble opening an IFC file in Revit. Have you tried using Link IFC? The open source updates export and link, not open. Also, sometimes "auto-join" causes trouble if you really need to use open vs. link - you can try turning that off (it should also import faster); similarly, you can turn off correcting lines that are slightly off axis. If none of this works, send us the IFC file and we'll take a look. Regards, Angel.


  • Help Documentaiton would be good
    Brian Renehan | avril 08, 2016

    Hi Guy 3 Items I can identify: 1- There is no help documentation for the plug-in. In the export options, we have so many options, but no in-dept. explanation of what they do. Second: 2- We need an option to export using the Project Startup point. It is common that we don't want to use the Survey Point. Note: we need this option to get BCF to work. 3-The export is very slow, and locks out the file during the export. I have a person here at work, have an error on their local file while I was exporting. The export takes several minutes.


    Angel Velez (Editeur) | mai 03, 2016

    To the help documentation point: there is an HTML help file that comes with the plug-in that explains the help options. It can definitely be improved. We will definitely look at the central file / local file issue on export, but would suggest for consideration to export from a local file to minimize the load on the central. Regards, Angel

  • IFC Export Classes subcategories
    Rikard Matson | mars 15, 2016 Téléchargement vérifié (Qu'est-ce que c'est?)

    Thank you for your great work, the exporter keeps getting better and better. I've encountered a problem with subcategories that isnt specifically set to an IFC Class in the IFC Export Classes schema. Subcategories with "{ Ifc... }" should look to the IFC Class of the main category, instead we found these subcategories wasn't exported at all. It could be hard to keep track of all subcategories used and to update the Export Classes schema all the time. We haven't experienced this before, and it seams to happen randomly. Anyone else having the same problem?

  • IFC export with Project North is essential feature
    Sergej von-Bagh | février 01, 2016 Téléchargement vérifié (Qu'est-ce que c'est?)

    If you can push forward the option for exporting with Project North setting, that would be GREAT. It's possible to edit IFC file with notepad to change from True North to Project North, as a workaround. Exporting with Project North setting is essential feature in most of our projects with IFC files.


    Rikard Matson | mars 15, 2016

    Hi Sergej! To export the IFC in different coordinate settings one can always use different sites defined for specific needs. I use two sites, one defined in world coordinates and one that is an exact replica of Revit Internal. By switching sites we can export IFC-files in both the project specific coordinate system and world coordinates. I think this is a workaround that doesnt hurt too much. All the best //Rikard


  • I have a problem with shared coorinates and model placement when importing IFC
    Kristoffer Tungland | janvier 27, 2016 Téléchargement vérifié (Qu'est-ce que c'est?)

    The problem is that Levels and internal origo in doors windows is placed at project base point but the rest of the model is placed at survey point. We need the model to be placed at project base point not at survey point. I got the file from an Architect, is he doing somthing wrong with the export from Archicad, or is there anything wrong with the Revit Import? He says that the model is modeled at local coordinates in Archicad. When i open the IFC model in Solibri i get the site coodinates with latitude and longitude, they seems right. But when i import it i looks like the model is placed at the site coordinates not the local coordinates. If i click on objects in Solibri i get Global X and Global Y coordinates with close to zero mm that i think also is correct! Do you have any experience with this problem? Another thing that fails is that some room origo is placed at wrong room bounding. This results in duplicate in rooms and som bounding does not have rooms. Can you choose the origo placement in Archicad or is this a Revit Import problem? I hope IFC exchange will be the way to go between software. Keep on supporting it Smile

    Good day, I was wondering if there is a possibility to export a family with 2D lines from Revit to an IFC format. I tried activating the 'Export 2D plan view elements' option but had no success. Can anyone tell me if what I'm trying to achieve is possible and describe a workflow for this.


    Benjamin Agyemang | janvier 26, 2016

    Thanks for the feedback. Sure I can upload a sample file. My aim is to export a revit model to IFC with different types of materials on walls using the split face and paint tool. Split faces are not exported with standard IFC settings.

    Hello! Did you get the materials show on IFC and if you did, how?

    Great work. However, I would like to export in another orientation then True North. Will this be possible? I need to import my IFC to a Facility Management system later on.


    Angel Velez (Editeur) | janvier 24, 2016

    Hi, at the moment it uses your True North setting, although we have a UI request to ignore this on export. If you want to temporarily change your true north and export, this would be a workaround for now. Hope that helps!

  • Importing IFC

    I want to know how we can import IFC file in revit using this app.


    Angel Velez (Editeur) | décembre 14, 2015

    This app seamlessly replaces the existing IFC UI. So you can use Open IFC or Link IFC as you normally would, without having to look for something in the Addins tab.


  • Reinforcement Import
    Anthony Mctigue | décembre 14, 2015 Téléchargement vérifié (Qu'est-ce que c'est?)

    I am currently using RAM Concept to design slab reinforcement which I have been trying to import into Revit via IFC. I was hoping that this add-on would be capable of importing the reinforcement objects into Revit such that we can properly document and schedule it as opposed to having a crude indicative layout. Are there any plans to add this functionality to this add-on and if so, what would the approximate time frame be?


    Angel Velez (Editeur) | décembre 14, 2015

    Hi Anthony, could you can send an email to the revit.apps alias so we can further understand how you are trying to document the reinforcement objects? That would let us figure out how best to meet your needs. Regards, Angel


  • Issues on Creating properties Sets
    Rui Gavina | novembre 02, 2015

    I created custom properties sets in a txt file, following the instructions stated in the example, and exported an ifc file, with ifc version 2x3 Coordination View 2.0. I have opened the file in solibri model viewer and teklabimsight and the custom tab and properties i set up don't appear. Does it only work in IFC 4.0?


    Angel Velez (Editeur) | novembre 03, 2015

    Hi, this should work for IFC2x3. Please send a sample small project and your custom file to revit.apps@autodesk.com and we'll try to give you further help.


  • Export propert sets problem
    David Morbin | octobre 29, 2015 Téléchargement vérifié (Qu'est-ce que c'est?)

    Great new feature 'export custom property sets' Works well on many things but after testing certain catagories i.e. Floors, Windows, ceilings and Railings they didn't seem to read the text file and export. Any suggestions


  • Linked Models from a Project - IFC exported with incorrect coordinates against the model (bind)
    Cheng David | octobre 06, 2015 Téléchargement vérifié (Qu'est-ce que c'est?)

    After generating the multiple IFC files that include Linked models IFC output, their coordinates are clustered among the Linked Models' IFC after reading them in but the project model coordinates were far off, Did the Projet Location, Publish Coordinates and still the same problem. Please advise.


    Angel Velez (Editeur) | octobre 09, 2015

    Hi David, I replied to your Revit.Apps email. Please send us a simple model that shows your issue and we will see how we can help. Regards, Angel

  • Compatibility Revit LT 2016
    L.J. Van Der Voet | juin 01, 2015

    The UI Exporter works fine (except for the UDPS list) for the previous versions of Revit LT (14 and 15) but isn't working for 2016 LT. The alternate eport UI menu won't appear when eporting IFC files. I have placed the UI addin files in both locations (program data & user appdata) after installing, same as 2015. Any suggestions? Thanks.


    Angel Velez (Editeur) | juin 09, 2015

    The Revit LT 2016 compatibility issue was fixed in v16.1.
