IFCViewer doesnt display this ifc model
It's not an issue with IFCjs specifically, as I can't seem to open it with other viewers either. Is there another viewer you've used to open this file succesfully with? If not, I'd think it's an issue with the IFC, not with IFCjs.

I've tested the IFC with the following viewers,
- BIMcollab Zoom it loads OK
- Trimble Connect it loads OK
- FZKViewer it loads OK (although is doesn't show the model but maybe is because the camera is far away from the model)
- BIMVision Fails
- Solibri it loads OK but it warns about some models are incorrectly located (see image)

BIMVisio latest version display this ifc model correctly
Even there are viewers that dosent display this ifc model, there are others that do it, so it would be great that IFCViewer was one of them
"Can't display" is a bit ambigous. Can you provide more information? The more you provide, the faster we will be able to solve it.
Can't display means file doesn't loads.
Good news @jstec,
With a bit of patience ifcjs was able to load the model

But it took 8 minutees and 47 seconds (in my machine).... May be something is not well configured in that IFC-
So yes - this IFC file is generating a lot of errors which is what is slowing it down. I am unsure if these errors are because of bugs in parsing or a problem with the IFC file. Will look into it
Thank you @beachtom for looking into
@jstec I will take a look too
The problem appears to be related to the use of extremely high values during boolean operations.
What it means? exemple: the problem appears when comparing A=B and A, B contains numerical high values?
It means that we are working on it to solve it. It's related to boolean operations when reconstructing the geometry.
