Open below floor issue

[Phil_C]

Hello All
I have a house plan with five floors. The first two floors are living areas, the third floor is the attic and fourth and fifth floors are access to an observation tower. On the third floor I have a small room for the stair well that is set to "Open Below". On the rest of the floors the view in "Perspective" "Floor overview" shows the stair way to the floor below correctly but on the third floor it shows a white plane instead. The top of the floor is removed correctly but what appears to be the ceiling of the room below is not removed. I have tried deleting the walls and redrawing them but to no avail. I also checked the defaults for each floor and I could not see anything different. Does anybody know what could be the problem?


Regards

Phil

Go to the floor below, select the stairway room and open the dbx. On the structure tab, uncheck "Ceiling above this Room".

Hello Joe
I tried that but it had no effect.

Phil,

Time to post the plan

Do you have any of those 0 layers in your ceiling or floor structure defaults, if so ,delete them.

Floors above the attic? The attic level will have different properties than a normal floor. Try making them all real floors and the attic can then be just an attic and not another floor.

Hello All
I have found the cause of the problem but I don't know how to fix it. On the end of the building is a garage with a gable roof that joins onto the hip roof on the main house. I have a room above the garage that is accessed via the second floor of the house. As soon as I delete the end wall from the room above the garage the stairway open below shows up correctly.

Sorry for the confusion but the proper Chief "attic floor" is actually floor 6 and is not used.

I could not find any 0 layers.

Attached is a slimmed down version of the plan but it still shows the issue.

By the way I am using X5 on Windows 7 64bit.
Thanks for the help

Phil,

There is no data in the plan.
You need to close Chief before zipping.

Hello Glenn
Don't know what happened there. I did have Chief open but the file was not opened in Chief. I have uploaded another copy I hope it works.

Phil,

It's definitely a Ceiling Plane. I suspect that it has something to do with the Roof Baseline Heights - possibly being too low. It would be interesting to see what would happen if you simply raised the roof about 500 mm.

Phil,

The solution is to check "Use Soffit Surface for Ceiling" for the Room above the Garage.

Don't ask me why - but it works.

BTW, If it was me I would raise the Roof Planes so that the Roof Framing rests on a plate on top of the Floor Sheathing. It's a lot easier to build that way.

Thanks Joe that fixed the problem with the stairwell but now the walls are transparent when viewed using a full camera placed inside the room. I can live with that I guess but it looks a little odd.

I will lift the planes up as suggested. You are quite correct it would be a lot harder to build with the planes cutting the floor like that.

This is one of those unexplainable anomolies. You could also uncheck ROOF OVER THIS ROOM, and all is well, but I don't know why.

Here is the wierd ceiling plane issue that Joe solved. Makes no sense. I believe there is another user who is experiencing same issue with his plan. Probably a bug.
