I have tested GH Player with VA with simple scripting.
IFC properties are not assigned to geometry baked by GH Player.
Probably it’s not bug. I think it’s just current limitation with IFC component.
I hope bake-related functionality of VA will be more improved as quickly as possible. It doesn’t make sense to bake elements manually and assign properties such as IFC and section attribute one by one. I know that VA component are working with basic component from Grasshopper only, but please consider most users are using popular plug-in like Elefront.
