@o-babii according to the bug fixes for Release 23.2.3.0 for Revit 2023 it says 'Fixed exporting parts in assembly with the wrong elevation.' but according to our testing now it seems that there still is a problem unfortunately

This issue exists also for Release 24.2 for Revit 2024

Hello @mahshidmotie,

Can you please provide more details about your case?
If it's possible for you, could you please provide the Revit file for which the issue is reproduced,
it will really help in investigating the issue.

The above is a view on Revit. after export in IFC we have the mis alignment.

if I remove the assemblies from revit, then the following is the IFC export:

@o-babii please let me know how I can share the files with you.

@mahshidmotie,
Often people use WeTransfer for such purposes, protected by a password.
Also if you have a link for BIM360 that would work.
If the file is not huge, or you can simplify it, you can just send me on email.
You can contact me at oleksandr.babii@autodesk.com

@o-babii Hi again :)
Any updates about this bug?

@mahshidmotie ,
Hi, this bug has been reviewed and fixed, I think the fix will be available in the next update, but I can't guarantee it, nor can I talk about dates.

@o-babii
Thank you very much. I would be happy to test.
What I recently realized is: the same behavior appears even when there is no assembly. So rails appear in wrong coordinates even when they are not included in assemblies: Revit 24 --> ifc 4.3

@o-babii
you can repeat it with the same test file I sent to you before.

@o-babii/ @AngelVelezSosa I've also made an issue post about this: #806

So the issue is still there unfortunately, pleas update us about the status, because this issue causes a lot of frustration/ unnecesary discussions in project teams
