Heightdifference between same railings from diffrent models after ifc export

[a.de.koning]

After exporting 2 seperate models to ifc, I ran into a difference in height between 2 railings.

When I copy one of the railings into the other Revit model there is no heightdifference. 

But when the models are exported seperatly to ifc and checked in Navisworks there is a heightdifference of 30 mm.

Only difference in Navisworks that I can see is "Railing height", one of the railings has a railingheight of 0,140m, the other 0,170m, 30mm alright.

"Railing height" settings in both Revit files are the same.

Does anybody have any clue of how to fix this?

Wild guess: 

IFC Export Setup Options...

Hi barthbradley,

Thx for your fast reply.

I always use a custumized setup with my own settings.

Just to be sure I saved and reloaded this setup (json) to both files, unfortunately this made no difference.

Exporting in batch with one and the same setup also didnt do a thing.

I also exported both models using the "In Session Setup" and again, still no change

Hello,

What is the Revit version being used ?

Could you share those projects so we can give it a try ?

Could you also share the resulting IFCs files and a screen shot highlighting the issue ?

Thanks

Regards
