Hi,

I'm trying to convert IFC with convert2xkt but some ifc have this issues. And I can't convert them.

Do you have an advance for me to find out where is the problem come from ?

comand on centos : #convert2xkt.js -l -s file.ifc -o file.xkt

OUTPUT :
Error: RuntimeError: memory access out of bounds

Hi - this is likely to be caused by web-ifc, which convert2xkt uses internally to parse IFC.

That's a WASM module, which you may need to compile for the hardware you're running it on.

Thank you for your answer.

We already installed web-ifc because we had converted like 55 ifc but only 4 which didn't work.

I have WASM module also installed.

And I don't understand why it is not work due to "memory access out of bounds" for 4 ifc. I don't know how I can do.

convert2xkt_cjs_js

This error (RuntimeError: memory access out of bounds) from this function "LoadAllGeometry(modelID) " but I watched deeply and I don't see why. ( code in convert2xkt.cjs.js )

Any tips for me ?

Hi, this is a problem with web-ifc, which is the third-party component that convert2xkt uses to convert IFC to XKT - best to raise this issue with that repository: https://github.com/tomvandig/web-ifc
