I deconstructed the door then rebuilt it.
Rimworld how to see roofs.
Areas can be designated to have a roof or not have a roof by drawing either a build roof area or remove roof area.
On the bottom right corner of the screen are a bunch of buttons that toggle certain options and overlays one of them turns roof display on.
A pawn assigned to construction will automatically build the roof when there are enough structures in place to allow it.
So in my case i had expanded the room and 20 of it was left unroofed.
This means that the largest square room you can have is 10x10 internal.
The build roof area allows the player to designate an area which will be covered by thin roofing once a surrounding wall is constructed.
The first icon in the bottom row is a picture of a house.
This this is the way to do it.
Adds customizable roofing with transparent greenhouse roofing and photovoltaic solar roofing.
If you removed 2 entire walls and the corner between those two sides last then that roof was too far away from any other supports.
Designating such an area will also remove existing thin roofs and thin rock roofs when applied but thick rock roofs will remain intact.
The no roof area allows the player to designate an area which will not be covered by thin roofing once a surrounding wall is constructed.
A ignore roof area will cause pawns to not alter the roof in a specified area.
Keep in mind each roof tile needs to be within 6 range of a wall to not collapse.
There is two rows of icons in the lower right of the screen.
This is useful for things like.
When you click that all the roofed tiles on the map that you can see not hidden tiles show up with a green overlay.
A build roof area will cause pawns to build a roof in the specified area.
Larger roofed areas can be built with the use of interior walls as pillars.
It was a wonderful day that one of the recent alphas i think a15 included this option.
Indoor roofs are automatically built by builders.
Reworked from vendan s original idea.
Light green for constructed and thin roofs and dark green for overhead mountain roofs.
A roof collapses if there s no support rock wall within 6 squares of the tile.
This triggers a room check and the builder immediately started roofing the new section.
Removeing mountain roofs so i try to remove the mountain roofs so they don t collapse by declareing a no roof area but on some tiles it will never be possible to declare that area and if i let the roof collapse and remove the debris it just collapses again presumably forever since i tried removing it 15 times and it still collapsed.
It seems the roof building is triggered only upon completion of an enclosed room.
To build a roof outdoors a build roof area must first be drawn.
