Hi James, I don’t think there is any way to back feed information into MVO objects, my guess is there never will be. What you are doing is exactly what I had done in my office, but in the end I have to do a vardump from REQUEST (“Properties_Of_Parent”) of a Label object so that I can save the list of properties into a TXT file, from which the MVO formulates the list. This obviously prevents you from having an up to date list of properties if you change them very frequently; so you would need to have a robust vardump Label object allowing you to update the TXT file without much hassle.
I wish GDL allows us to access the IFC Scheme Set/Property Tables.
On the other hand I believe Applecore is working on a similar object, should you be interested.
