Save UV mapping to ifc style

edited September 2024 in General

I'm trying to save the UV map to the style--and coming up with an error.
Anyone have any pointers?
I'd like to be able to open the ifc anew, and have the uv mapping correct--if that's even possible.

    This is for sure the holy grail,
    Btw I can't see anything in your video not sure if it is just me?

    For sure. I believe it's possible though... i've done it before. The button is not in the UI, but the operator's there.

    @theoryshaw Did you see the gif in this commit? It worked for me.

    Triangulation!.. that's what i forgot. Thank you.
    It did take the assignment (well most of them.. not all), but when i saved, and tried to open the .ifc file again, i got the following error...
