windows and doors not rendering properly

[craigliesinger]

Using web-ifc in Angular app - loading IFC file from Firebase. All seems to go well, except windows and doors from model not rendering properly:

Example of screenshot from same model in other application:

I can't see anything clearly identifying the problem in the console:

Trying to show some property details from the IFC file (but I'm totally new to IFC, so not sure what information is really valuable here :) )

Trying to troubleshoot this a bit more (without the C++ / WASM skills to try fix on my own)... I notice with latest release with object highlighting & properties that the window geometries are being parsed as ifcWall (Wand-025):

Exploring the IFC I see in ArchiCADProperties that there is a property 'Überobjekt-ID' with value 'Wand-025' (Wall 25).

So seems somehow the parser is passing this 'upper object' or somehow getting crossed? Or perhaps the IFC is somehow prepared incorrectly (I'm not the author of the IFC file)... but It loads properly in other viewers so I assume its fine.

Maybe I'll find some time to try and get brave enough to jump into the C++ but for now I thought this additional info may be of some little help

Hi,

This is an interesting issue. There could be a couple things going wrong, but its hard to investigate without the model.
You can contact me on discord and transfer it privately, or attach it here.

Without the model, I can only guess.

Sure. Thanks Tom. You should be able to download file here: https://firebasestorage.googleapis.com/v0/b/ziegelwerkstadt.appspot.com/o/houses%2Fhouse2%2FH01_Flachdach_Index01.ifc?alt=media&token=c3f08ffd-b814-4ab8-a486-d671046724b6

Hi, this model will be fixed in 0.0.20

[craigliesinger]

I think there may have been an issue in the solution fix being pushed out with .20? I've tried your example app in web-ifc repo and a Svelte example I made that also uses web-ifc 0.20. I still get original result:

Indeed my fix was incorrect, should be good in version 21. Let me know if the problem remains!
