Can't help with what you're trying to achieve, but fwiw, if it's "demolished" it wouldn't exist anymore. "To be Demolished" is correct if it's still showing up in the drawings/model. It's not the same as "remain as existing" or "to be new" - which wouldn't be visible either - if it's not new yet, it doesn't exist

Hope that's not too pedantic - I do think that sometime's Archicad's terminology is not quite right, but on this occasion I think it's correct.
