Disappearing Floor

[Max Power]

One half of the house finishes on the 3rd floor with the flat roof terrace.
The other half continues to the 4th floor.
The wall between the terrace and the rest of the house behaves automatically as an attic wall and the 3rd floor inside the house does not behave as a room (can not be greyed nor opened for revision). The joist between 3rd and 2nd floor are automatically made half the size of the joist in the rest of the house.
What to do?

Open the attic wall and uncheck "attic wall" or redraw the attic wall manually as a normal wall. Check for other such walls also.

I did uncheck the attic wall, but the rooms are still the same (could not be opened for revision) and floor structure is still half size.

Yeah I had that happen earlier today. Deleting and redrawing walls and checking walls eventually did it.

You have to use the highly developed technical method we used at Intel to get balky equipment to run: screw with it until it works.

Or you might try going to the framing dbx and making your ceiling joists on the floor below 2x10's or I-joists.

Thank you all for trying to help.

My biggest problem is that all the rooms on the floor in question refuse to “grey out” when I click on them. Would manually changing the joists rectify that problem?

[Allen Brown]

Generally when I cannot select a room,(grey out) it is because it is not recognized as a room, such as chief sees it as still attic, or maybe it has an open wall section to the outside world. Did you create another floor, or did you start drawing walls in the attic? That has created that same problem for me, and I had to delet it and build that floor over.

The only thing I can contribute is to open some of the walls in the areas that won't gray out and make sure they are not checked for "No Room Def."

[Max Power]

I'll try all the above today!

Thanks for all your advices.

EUREKA

It worked!!!

Persistence paid of.
I just kept on trying and it worked.

[Allen Brown]

So Max,

What exactly did you find to be the error??

On the terrace three sides are railing and the fourth (the wall in question) was supposed to carry on for another floor.

The wall between the terrace and the rest of the house appears to have been confused which side of the house to side with.

I just kept on redrawing it until he chose the right one!
