Keeping exterior trim outside!

delete all the trim the place it again one wall at the time holding down shift and see if you can get it only exterior this way

in this case it seems to be because there is part of the inside of house with removed floor which i think there was some way around but i can't for life of me think of way to explain how to go about that since its often lots of fiddling for me too to fix :sweat_smile:

but yeah basically that part is not recognized as room since it has no floor so that is why the trim comes in

you need to somehow redo that part so the room is recognized (place new room there perhaps and redo that part of build? idk i can't remember what the fix was last time i had this issue)

I think you need to check your rooms, one of them might not be a room so the game doesn't recognize that there is an inside and an outside. But, yes, the easy way to fix it is to just delete it and then place it on outside walls only with shift click.

Ah ha thank you both. Yes, that part of the second story is not recognized as a room.
I notice that in the part of the second story that is recognized as a room (the part that has the floor) there is an invisible wall here over the stairs. Or some other thing that's causing the game to recognize that as the edge of a room even though there is no wall.

When I try to make the open part of the second story into a room with no floor, I would really like to be able to use that invisible wall over the stairs as one of the edges of the room.
I am able to make a room using regular walls and delete the floor, but I'm left with a visible wall in that place over the stairs where the invisible wall was.
The closest I can get is by putting a piece of fencing over the stairs. I don't like the look of fencing floating in midair though.
Fortunately it won't snow in there, since there is also a third floor... but does anyone know how those invisible walls over stairs work, and how to get them as part of a room I draw?

hmm... maybe next I'll try making a platform or a flat, those are recognized as rooms even though there are no walls... I wonder if they will continue to exist when the floor is deleted. will try that

Phew, got it. Here's how, for the sake of anyone who finds this thread later
(like, for example, me, the next time I have this problem)

Forgot to reduce the size of the screenshots so they may take a little time to load.

I was getting frustrated with this build so I went over to Babs Builder's save and made her a basic version of the problem.


Back to the lounge, same process.
