Dimensions of IfcOpeningElements are out of control?

[JSN]

Hi, what is the reason that sometimes IfcOpenings (also from Doors and Windows) are getting ridiculous absurd dimensions?

This is a model I received ...

... and this is what I get with the same components.

I know for some time there is/was a problem for some time with automatically  created openings but it's new for me to see this also on doors and windows. So I am wondering what is causing this behaviour? Is it a setting or a hidden option that's triggering this effect?

[JSN]

Any updates?

[JSN]

No ideas?

[JSN]

Though I guess there won't be an answer I am curious why some doors have such openings as well.

it makes coordination unnecessarily more complicated.

[JSN]

Here I am again. This topic is a returning matter in every project. Would be great to get a reply on how to tackle this ....

@JSN,

Can you check how it looks in an IFC Viewer before you import the IFC into Archicad?

I am curious whether it already looks like this in the IFC Viewer (which would indicate the cause is in the IFC Export process in Revit), or if it looks normal in the IFC Viewer, but looks like this in Archicad (which would indicate the cause is in the IFC Import process in Archicad).

[JSN]

All those IFC files have been created by Archicad.

Screenshots are from IFC Viewers like Solibri, Desite or BimCollab.

No involvement of Revit. No import into Archicad.

It is an Archicad Export Issue.

OK, sorry, that must have been an incorrect assumption on my part because in your original post, you said you received the file, and I assumed you were working in Archicad and received it from an engineer working in Revit (lots of assumptions, sorry about that.)

I will forward this to GS HQ.

[JSN]

True, the initial post is lacking details. My assumption was that this bug is well known.

So what I should have added is that this issue is bothering us in coordination context since a while. However I can't say why and when it is triggered as in sample files and small projects things often look alright and suddenly everything is out of control.

For created openings, there is in fact a workaround but talking about objects we don't see any options.

IfcOpenings and their relations are powerful in the context of model checking but not if they are transformed into some infinite spaghetti boxes.

I am not sure but I think at some point in the past, a few years back, this used to work properly but could be that I am mixing up memories.

When you export IFC, into the translator, you must unflag the Ifc Opening Element. See the image attached.
