That’s actually a really interesting take (even though the OP software is not really for that). How would you _like_ to design this treehouse? Is the particular tree relevant here (do you have a photogrammetric scan of it for insrance) or are you planning to design a generic shape you are confident can be installed on the target trunk? Is the treehouse more of a plank platform for one or an actual multiroom house? Is the budget closer to 5$ or 50 000$?
