Villa Savoye - IFC Missing Window & Opening

[bernd]

for me no window is missing in IFC file ...

[yorik]

I think likely the problem is in the freecad file, not the exporter...
there is some gruesome pyside2 mismatch on my debian machine right now so freecad doesn't compile and i can't test right now...

Some finding...

Happen to just open the exported ifc in FC and all windows and openings are there

Maybe I need to compile the ifc++ using the latest Berd's repo ?

Maybe I need to compile the ifc++ using the latest Bernd's repo ?

Perhaps if this is an issue, we should think about adding ifc++ or any other relevant 3rd party software to the About output?

[paullee]

Yes maybe About ifc++, my version is Bernd's repo download at 12.10.2019

And another finding at ifc++.

The window is there, at a particular angle, a slight impression is noted, need to look at the image closely

Just no opening is created ?


Zoom in, the window can't be seen no more.

in the title of ifc++ window is some version info.

OK, it is strange

Download and compiled the latest git and still the same in IFC++, No Opening, barely noted the Window is there

Tried BimServer 1.5.162 - Opening is there

IFC++ problem On Fedora 30 ?

Display Driver ?

problem is not Ifc++ but the export from FreeCAD ... see screen. On the left the ifc is exported from this model (https://forum.freecadweb.org/viewtopic. ... 86#p360436) on the right it is the ifc you posted here (https://forum.freecadweb.org/viewtopic. ... 10#p360684)

Thanks for testing .

The strange thing is the ifc I made and posted here :-

- In IFC++, No opening for that particular window
- Window object is noted in IFC+= tree, and barely observable

- IFC imported back to FC ; Opening is there

- Ifc imported to BIMserver, opening is there

Same ifc file !!! ???
