Describe the bug This is part of ifc model, but viewer render not correct. Xkt model also converted from this model.

Screenshots Original: image

Desktop (please complete the following information):

I don't understand it a viewer bug or wasm parser. My debug brought me here, but then I can't check the data is valid here. https://github.com/xeokit/xeokit-sdk/blob/02576b0be6dec9c4d8fc0f45bd408d4ffc05e449/src/plugins/XKTLoaderPlugin/parsers/ParserV10.js#L402-L409

What else can I provide to find the problem?

Additional context xeokit-sdk version 2.3.9

This bug is likely to be a geometry processing bug within the 3rd-partyweb-ifc library, which is used within WebIFCLoaderPlugin to convert IFC. Unfortunately there's not much we can do on our end, since we just wrap that library.

In the meantime, I'd suggest using our other conversion tools, which may give better results - see here: https://xeokit.github.io/xeokit-model-conversion-tests/index.html
