Converting IFC to XKT

[nguyenngocdue]

I'm currently learning how to develop a Revit-related application and I'm using the Xeokit SDK.
My workflow is:

1. Let the user upload an IFC file to my web application.
2. I then convert the IFC to XKT to reduce the file size.
3. Finally, I render it using Xeokit.

However, at step 2, I'm not sure why the conversion from IFC (around 100MB) to XKT is taking so long.
Here is the backend code: I upload the IFC to MinIO, then retrieve the file and convert it to XKT.
Can you take a look at the code and give me your feedback?

hi @nguyenngocdue , thank you for your question and sharing with us more details about your project!

Getting a bit ahead of my colleagues from the code dev team, I can already state that this conversion path relies on a third-party library, namely web-ifc which we unfortunately are unable to properly support. From time to time we find and fix some issues there but we can't really guarantee. This is why we have this big warning at the beginning of the xeokit-convert Readme:

Does this help any further for now?
