  • Export Design Options
    Ramón Jesús González Márquez | 八月 01, 2019 验证的下载 (这是什么?)

    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 (发布者) | 八月 01, 2019

    Unfortunately, only the primary design option is currently supported.

  • Where is V
    Shafeekh Melangadi | 七月 25, 2019 验证的下载 (这是什么?)

    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 (发布者) | 七月 29, 2019

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

  • 2019.2.0 not working properly
    Magnus Jeppsson | 七月 04, 2019 验证的下载 (这是什么?)

    I rolled back to 2019.1.0 because when exporting with 2019.2.0 it can take anywhere between 1 minute and 1 hour, the file size sometimes skyrockets, elements not visible in view are still exported when "only visible in view" is checked. That's what I can think of right now. Wouldn't recommend 2019.2.0 for now. 

    Ramón Jesús González Márquez | 八月 01, 2019

    I had to do the same, but in my case because the time of exporting moved from minutes to several hours on the same files....

  • Split elements options are great
    Laurens Linthout | 六月 26, 2019

    Ideal for exporting files to 3rd party contractors

  • Much needed
    Olivier Pellegrin | 六月 11, 2019 验证的下载 (这是什么?)

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

    Angel Velez (发布者) | 六月 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 | 五月 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 | 三月 13, 2019 验证的下载 (这是什么?)

    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.

    Klas Torstensson | 四月 03, 2019

    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.

  • New naming of ifc objects?
    Tomas Westerholm | 二月 06, 2019 验证的下载 (这是什么?)

    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 (发布者) | 五月 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 | 一月 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 (发布者) | 二月 01, 2019

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

    Edwin Bosma | 二月 05, 2019

    Awesome. Thanks!

  • Plugin works only when revit display language is in english
    Elton L | 十二月 04, 2018 验证的下载 (这是什么?)

    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 (发布者) | 十二月 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.
