I modelled my whole house including very piece of furniture. It is very “finicky” as you describe. It’s good enough for my amateur use with manual clicking. (There’s probably a programmatic option that I don’t know). However if I was a pro contractor it would probably not be the best.

I did plan custom designs that my contractor used. It’s also great when I want to get a new desk or sofa or whatever so that I can visualise everything first. Possible to make pretty realistic 3d walk-through videos that would be fine on any design tv show.
