  • General coordinates do not coincide
    Anton Terentev | novembro 30, 2021 Download confirmado (O que é isto?)

    Old and this export does not coincide coordinates

  • Import IFC
    habib safa | maio 17, 2021 Download confirmado (O que é isto?)


    everytime i need to import an IFC in revit 2019, i need to uninstall the app otherwise revit will not import the ifc file. 

    Any idea how to solve this issue?

  • Settings not sticking on "Advanced" Tab
    Ihsan Gin | outubro 28, 2020 Download confirmado (O que é isto?)

    The last two checkboxes (The ones deal with ifcType and ifcEntity) on the Advanced tab of "Modify Setup" does not seem to stay on after an export. 

    Is there a reason for that? 

  • v19.3 Warning Asking to Ungroup Groups
    Mark Thompson | dezembro 04, 2019

    On version 19.3 of the exporter we come across an issue at the end of the export where warnings appear asking us to ungroup particular groups in our models because changes to groups are only allowed in the group edit mode. This did not happen in v19.1 so I am wondering why this is the case in this version. The instance parameter IfcGUID cannot be accessed through the Project Parameters to allow it to vary by group instance (assuming that is what is trying to be accessed). What are the implications of clicking cancel when we receive this warning (the IFC still exports OK)?

    Michel Alofs | março 11, 2020

    Correct, just faced the issue to. This needs to be corrected, and the IfcGuid parameter should be "Vary by Group"

    Angel Velez (Fornecedor) | março 12, 2020

    I'll file an issue for this - sorry I missed this the first time it was reported. There should be no real issues with cancelling.

    Andy Parrella | março 13, 2020

    I'm looking into this for Angel. I can't reproduce that with a simple file with groups. Could you send a small rvt project that shows the issue? thanks.

    Mark Thompson | março 30, 2020

    Hi Andrew, yes I shall send it to Angel. Many thanks

    Steffen Bergsø Terp | julho 28, 2020

    Hi, is there any update on whether this will be fixed?

    Good app, but you must acquire some knowledge about IFC and the exporter itself to understand why it's not working or why it's so slow! It all depends on the user that's exporting the Revit file.

    Low understanding/effort = Low quality guarenteed.

  • Export Design Options
    Ramón Jesús González Márquez | agosto 01, 2019 Download confirmado (O que é isto?)

    It seems it is not possible to export Design Options. For certain projects it's an excellent tool and not being able to export to IFC other design option but the primary seems odd.

    Any ideas?

    Angel Velez (Fornecedor) | agosto 01, 2019

    Unfortunately, only the primary design option is currently supported.

  • Where is V
    Shafeekh Melangadi | julho 25, 2019 Download confirmado (O que é isto?)

    What is the differance between V and V ?

    My contractor Submitted the IFC file with version V but I can not find that version here..!!

    Angel Velez (Fornecedor) | julho 29, 2019

    I believe that might be the "vanilla" IFC code from Revit v2019.2.

  • Split elements options are great
    Laurens Linthout | junho 26, 2019

    Ideal for exporting files to 3rd party contractors

  • Much needed
    Olivier Pellegrin | junho 11, 2019 Download confirmado (O que é isto?)

    Very useful but why it is not integrated directly in the Revit insall?

    Angel Velez (Fornecedor) | junho 13, 2019

    This is included in out of the box Revit. This only allows for updates after the software has been released.

  • Error: Missing elements in the IFC file, because the revitworker not are finished calculating
    Asger Petersen | maio 07, 2019

    The plugin should not export, before the Revitworker is finished calculating.


    We are use Structural Connection.



  • Fairly quick export

    Fairly quick export.

  • Exporting to shared coordinates
    Kong Hoang | março 13, 2019 Download confirmado (O que é isto?)

    So, linked in a model and aquired coordinate system, then tried to export to ifc.  Then tried to link ifc into earlier version of revit (2016) for coordination, and will not drop into the right location, no matter which coordinate export setting I choose (I've tried them all). Project is not ready to upgrade to 2019, but realise this is the obvious answer.  The 2019 user can't downgrade to 2016, so we are in a bind.  Have to get the ifc export to work for coordination workflow, which this is holding up.  Any ideas?  Thanks.

    Have the same kind of problem. When exporting to IFC with "Current shared coordinates origin" the rotation becomes wrong, its true north instead of project north or if its vice versa. This problem was not in 2018 release of addin and/or Revit 2018.

    Daniel Pribula | novembro 05, 2019

    I thought I mention my observation here. I have a similar issue as Klas described. I'm using Revit 2019 of course as this is about IFC 2019 plugin. The situation with problems is: I think plugin is working correctly to some extent: I have exported IFC model with IFC 2019 plugin - Project Origin set to "Current shared coordinates" and loading it into Navisworks. - Navisworks Application Menu - Options - IFC - Revit IFC - checkbox off - model is loaded to correct Shared coordinate X and Y but Z is 0. Orientation is correct. - Navisworks Application Menu - Options - IFC - Revit IFC - checkbox on - model is loaded to correct Shared coordinate X, Y and Z. Orientation is incorrect. Instead of True North, a Project North is used. I have exported IFC model with native Revit IFC export and loading it into Navisworks. - Navisworks Application Menu - Options - IFC - Revit IFC - checkbox off - model is loaded to correct Shared coordinate X and Y but Z is 0. Orientation is correct. - Navisworks Application Menu - Options - IFC - Revit IFC - checkbox on - model is loaded to correct Shared coordinate X, Y and Z. Orientation is correct. Conclusion: Navisworks implemented a fix for the incorrect position of IFC file export from Revit. If other software (like BIMsight) is used, using IFC file export from Revit with a plugin or native IFC export, IFC model will be positioned to wrong Z coordinate. Unless the other software has "Revit IFC" fix implemented. IFC 2019 plugin has no good use to me. Please, correct me if I'm wrong.

  • New naming of ifc objects?
    Tomas Westerholm | fevereiro 06, 2019 Download confirmado (O que é isto?)

    We use ifc-file from Revit to generate materiallists and price calculation.  The program for we use for this calculation have "lost" the connection to beams, colums, doors, windows and all types of walls in ifc files from Revit 2019. We have to use 3 days to reconnect all the objects. I asume this accurs due to new naming in 2019 versjon. If this is correct then why, and can we expect this type of change often in the future? 

    Angel Velez (Fornecedor) | maio 09, 2019

    I'm sorry I missed this before. Can you send a file to revit-apps with a more detailed description of the issue? I don't know what renaming may have happened in 2019, and we don't expect to do that often.

  • Override floor
    Edwin Bosma | janeiro 31, 2019

    When we export our buildings we have to assing every element on a floor to that floor (ground floor, first floor, etc.), by modeling them to a certain building story in Revit. Is there a way we can add a parameter that overrides the floor it's exported to? For instance a wall is set on de building story First Floor but for some reason in the IFC we want it to be assigned to the Second floor without changing de level settings of that element in Revit?

    Similar to how you can overwrite the name of a family with the parameter IfcName.


    Angel Velez (Fornecedor) | fevereiro 01, 2019

    This isn't possible yet but it is something we are working on.

    Edwin Bosma | fevereiro 05, 2019

    Awesome. Thanks!

  • Plugin works only when revit display language is in english
    Elton | dezembro 04, 2018 Download confirmado (O que é isto?)

    This plugin works only in revit is displayed in english. If i use revit in ex. italian the plugin saves an empty IFC file. It has been this way for past couple years... Please fix it!

    Angel Velez (Fornecedor) | dezembro 18, 2018

    There is a workaround for this. Go to R > Export > Options > IFC Options. Look at the name of the IFC export classes file at the top. Find it on disk, and delete it. Then press the "Standard" button. This will reload the file in your local language, and export will work.
