Not able to load IFC-file, possible due to `Unexpected profile type`

[ThomasTJdev]

Big congrats on the library - this is really awesome!! I have been testing the lib with the PR at threejs (mrdoob/three.js#20598), but I can only get the example IFC-files to load. I have tried with some of my other IFC files, but with no luck. These are files works when converted from IFC to gTLF.

When importing a file, this is the result from console.log:

Can I provide any other debugging info for you?

[agviegas]

Thanks @ThomasTJdev! We will implement IfcIShapeProfileDefs these days. We don't need additional information; once we make the first step, we will let you know to see if it's solved.

[ThomasTJdev]

I have tested various other IFC files and I got another Unexpected profile type:

#56335= IFCCIRCLEHOLLOWPROFILEDEF(.AREA.,'AirTerminal_\X2\00D8\X0\160_Type15',#56334,94.9999999999999,15.);

[agviegas]

Thanks for the notice! I'm finishing geometry optimization this weekend, and these issues with the profiles are the next bullets in my list

[tomvandig]

Both IfcIShapeProfileDefs and IFCCIRCLEHOLLOWPROFILEDEF are now implemented, please check out https://tomvandig.github.io/web-ifc/examples/viewer/index.html (might need to clear cache & refresh to download the new wasm binary)

[ThomasTJdev]

Thanks @tomvandig. Using your link the console shows that it loads fine, but no model is shown. I'll try to pull and compile later for a local test.
Thank you for fixing the issue!

[tomvandig]

Hi Thomas,

I'm sorry about that, that's unfortunate.
I believe both element types are implemented correctly now, as I can see them properly on other models. I believe your problem may lie in the coordination of your model. If your model is very far from the origin it may not be visible, even though it is loaded properly.

I will add some normalization to the viewer so you can check if this is indeed your issue. If it is not, I will need the model available to be able to help you further.

Cheers.

[agviegas]

Just for the notice, centering the camera to the geometric elements is something we have already implemented in web-ifc-viewer.

[tomvandig]

As a workaround, I've added normalization to https://tomvandig.github.io/web-ifc/examples/viewer/index.html in the latest deploy. If you still can't see your model, something is seriously wrong and we should investigate further.

Thank you @tomvandig! It works. I have tested with various models from different design teams - they load correct and fast. Great job!

Now when my models can load, I'm coming over to the web-ifc-viewer-repo 😉

[agviegas]

@ThomasTJdev Great! Keep in mind that these changes need some days to reflect on the other repos. Also, beware that the last changes regarding IFC functionality are in web-ifc-three.
