If I remember correctly, IFC Ex3 exports allowed to export the length and dimensions of ducts/pipes/cable trays. From what I can see that is not exporting anymore with the base quantities option. Is this normal ?
In the IFCs I am getting with this plugin I do not get correct door openings. The same model exported to IFC from Revit 2022 has correct door openings. Please see this post, including test files: https://forums.autodesk.com/t5/revit-architecture-forum/door-opening-missing-in-the-ifc-generated-from-revit-2021/td-p/10884742
When can we expect 2022 version?
It is part of the Autodesk Desktop up for Revit 2022 and 2023 - you don't need to come to the App Store to look for updates.
The Add-In works just fine.
dint find useful. export IFC from NAVIS 2021 then tried to open and link in revit 2021 but its blank, nothing comes in file. and the IFC created from NAvis has like 3kb size that also not seems good. please help if i am missing something
Please contact firstname.lastname@example.org if you are having issues getting IFC export to work. Often when you see empty IFC files, it is because your export options table is either set to everything "Not exported" or to a different language. To fix this, find your export layers file on disk, delete it, and recreate it by pressing the "Standard" button on the dialog. At that point, your IFCs should show up. Try that, and if it doesn't work, email us.
It solved when I deleted the file from the disk, but only after I purge the file. Thank you!
