I thought I could place it myself, I was going to be an Internet about it and drop a fence right in the middle of this roundabout with like ten buses going around it, but I'm stuck on this "finding a place in the world," so I don't really get the purpose of this app at all.
I have no way to distinguish if I actually am affecting this "world." For all I know someone is just modeling stuff, and when I draw a "fence" it goes and finds a random fence and says "here's the fence you made, yay for you!"
I have a feeling that's exactly what's going on here because I drew a small bush and it said "Thank you, the world needed 4 of those!".
Also take a look at where most of the trees were created at. Shoreline Amphitheatre. :)
First I drew a post box that I can (normally) see from my window. It tried to tell me it was a house, and I managed to cancel out by accident in my search for a "not a house" option.
Second I drew a bush with lots of bubbly bits - very mario-esque - but it turned it into a spheroid.
Confusing if this is what was intended; but the UI was pretty.

It uses an AI do figure out what you meant from an abstract drawing.
In the Console if you bring it up you can see the issue. It's unable to connect to the socket it's trying to connect to. So a live bug.
