Re: Open floor over stairs deletes them and makes roof enter enclosed room
I think I understand what you are trying to do. You are trying to create an open stairwell. To get those to work, try this.
1 - On the second floor above where the open stairwell will be, draw walls or a fence around the area you want to be open. Then delete the floor. You should be able to see the floor below through the hole you just made.
2 - Change the wall to a fence across the front of the stair, where the top landing will be. The other sides don't matter but the top step needs a fence for the stair to place properly.
3 - If you are planning to use a bent stair, put the stair down in the yard or somewhere you have enough room to rotate the stair. (I do this because I always end up with my bent stairs facing in the wrong direction.) Then configure the stair how you want it.
4 - Once you have the stair configured how you want it so it will fit the hole in the floor you made, then move it into the house on the floor below the hole. It should place properly and the top landing will remove the fence section automatically.
If this doesn't work, come back with a screenshot or two so I can see what your exact build looks like. If you like, you can upload the build to the Gallery and let me know here and I will be happy to download the lot and take a look at it.
Hope this helps.
