Same problem! First project: I used the "trace" function to place walls to match my plan - it all looks fine but no floors are created (just grass!).
I assume the software does not consider these "rooms" for some reason. What is the right way to do this and what criteria does the software use to identify a "room"?
If there's a correct way to do this? I'm not so far in that I can't start again, but what am I doing wrong?
Thanks!
