Shift on certain objects

[moovida]

I am not sure if this should be asked in the sdk project. In case please redirect me.

I am new to xeokit (huge congrats, this is quite awesome) and just tested a conversion and visualisation of a small water supply pipeline. I am experiencing shifts in some objects. The same shifts are not occurring if I look at the ifc file in different ifc desktop viewers (ex. Bimviewer).

To have a better idea:

you can see that the hydrant and the lower elbow are shifted against the pipes they should be attached to.

Did anyone experience something similar? I can't understand if I am doing something wrong or if it is something in the conversion from ifc pipeline.

Any idea on how to check this would be super, thanks.

With BIMVision for example the ifc looks like:
