Blender now supports IFC export

( BTW, I have thought about modelling Ronchamp but find I am far from understand feature in FC for curve surface, want to tackle that ? )

Don't distract him. He is doing great with coding, right now.

You are very correct. And like you says, he should be drawing more attention of architects in blender community

FreeCAD really has per design problems on huge modells with ten thousands of objects in the TreeView.

@moult:
Do you use BlenderBIM as your standard IFC viewer as well?

[Moult]

On Mac and Linux, the BlenderBIM Add-on is the IFC viewer of choice for me. On Windows, it depends. I often open it in XBim as well as the BlenderBIM Add-on, simply because it's faster in XBim (IfcOpenShell still has some pending bugs for multiprocessor import - so I can't rely on it yet)

I'm not sure which GSoC IFC code you're referring to, but if you're referring to BCF code, then I indeed am using code, see: https://github.com/podestplatz/BCF-Plug ... D/issues/3

yep this was done in a GSoC in 2019 by Patrick. See https://forum.freecadweb.org/viewtopic.php?t=35465

BTW: initialy he wanded to do FEM GSoC but there was a student already and bcf was the most useful outside FEM for me, thus the idea came up https://forum.freecadweb.org/viewtopic. ... 10#p269906 lately very very good choice of the FreeCAD community to go for the bcf implementation. Thanks to yorik too who did most mentoring work.

But it is much faster than FreeCAD. I started to use it in addition to ifc++ on Linux and BIMCollabZoom on Windows.

1st Test with BlenderBIM for import Villa Savoye IFC.

Looks Great and Fast!

Any idea how some window / window glass pane are not showing correctly ?

Thanks.

And anyone try to import the 210_King_Merged.ifc ?

Seem import after 5-10 min, there are numbers of item in the model tree but nothing on screen ?

Thanks.

sometimes if imported geom in blender is far from the origin you have to check clipping planes and try to zoom all.

[Moult]

Really appreciate the testing @paullee!

- The window is because BlenderBIM does not currently support import of multiple materials per single object (i.e. the geometry is correctly imported, but the lack of materials make it look wrong). I am interested if FreeCAD is capable of this, since it can be a bit finicky to support. This is now fixed, and will be available in the next release: https://github.com/IfcOpenShell/IfcOpen ... 38d79dcb91

- I haven't yet investigated the missing geometry. Will check.

- Can you provide the 210_King_Merged.ifc model? I'd like to see Otherwise, @carlopav's suggestion seems sensible.

Note that related to materials, this IFC4 file produced by FreeCAD seems to use IfcPresentationStyleAssignment, which has been deprecated and is invalid Yorik, if you're up to fixing that feel free, otherwise perhaps leave it on the bugtracker.
