This is definitely huge! Are you designing an exporter as well, that will keep/maintain the metadata within the same IFC BIM data structure? And will you change the string method of imported boolean metadata into actually being translated into bool types instead of strings? I guess that will be important. I can surely see great possibilities with being able to switch out a few BIM products in realtime in unreal, for then to click a menu widget button for exporting the model as IFC with updated selected content based on client wishes. Like in a configurator, and then export model back out with all data you need to actually do ingeneer work like calculating and placing orders based on that IFC export. I know this is a big digitalization feature that is spoken about a lot in the construction/architecture arena.
