Revit not ifc compatible

[MBBIM]

Im still working with 2015 LT and found IfcExportAs is not responding. I noticed this is also still an issue with the newest versions. So is Revit Ifc compatible like all the other software or still behind ?

Exporting to IFC should not be an issue.

Try forcing a system family from floor to roof.

Windows in revit are the worst. You probably noticed that hacks are commen use in revit. The curtain wall hack is used by many people to create windows. Im trying to do the right by doing wrong. Make the curtain wall a window Ifc class. Even is i change the export file and try to force a curtain wall into a window it partially works.

I don't think @loboarch needs schooling.  Have you checked his credentials?  He probably invented the "hack".

But he has no answer. I wil use the in place wall which transfers perfect to any ifc class.

After 30 years working with autodesk software i will not give up. Revit is a nice piece of software but some flexibility would be nice.

I am at a loss. The first question is as general as it can be, then a random comment about floor/ roof, then windows/curtain walls, and finally another random comment about in place walls. How are people supposed to answer your question(s)?

Its ok if you dont get it though my question was clear. Can i use IfcExportAs for all that is in revit to put it in the right ifc class. I was hoping somebody found a way but i know the answer is NO. A system family cant be anything else than Autodesk wants it to be. So a floor can according to autodesk never be a roof etc.. I wanted to change the curtain wall in a IFC class Window but thats not possible. Thank you for taking the time to read my lines.
