IFC - Questions from a beginner

Thanks for you input, @Moult. It looks like IfcOpenShell is the way to go. You also mentioned Speckle earlier – I’ll have a closer look at that later to see if that could improve the data transfer time.

Yes, definitely. All the new material data from the LCA app might as well be stored in the IFC file. But is there a good way to send that extra material data back to the building app? It is possible to create a new project from an IFC, but importing the new material data into the existing project would be ideal.
