adding a wall to a room area calculation

[tecnicheparametriche]

Hi all,
I have a problem, since I need to add the surface of a wall
to the room computing, even if the wall is somehow "outside" of it.

basically I need to remove the area of a stair from the upped
floor of a "duplex" apartment, but what remains after removing
is is just the wall, so revit excludes it automatically from the calculation.

See attached images..

the first is the starting situation
(what I want to achieve)

the second is what I am trying to do - move the boundary line to the face of the wall

the third is what revit does: the half-portion of the wall gets excluded from the calculation
but I want it in!

the wall is room bounding, I tried making it not room bouding and add a line
instead but it doesn't change.

the 4th is a try I did.
It seems that rooms DON'T ALLOW a portion to be LESS than 20 CM of width?
I tried just a boundary, and when it gets thinner than 20 cm... it disappears!

wow, don't tell me that 's a bug or something?!

We are using RAC 2010



Hope it's clear enough for someone to help!

crossing my fingers..


Stefano





thanks,

Try changing the "Sliver Space" setting. It defines how big of a gap the room calculation algorithm ignores.

Hi Mike

thank you very much,
so weird, I tried but it doesn't seem to care
if I change the setting,

Tried in a new file.
see attachments.

Did it work for you?

thanks in advance,
Stefano

Stefano,
it appears you are using the room objects to get your area calculations. The settings for room area calculation can be either face of wall or center of wall. What you are trying to do is force Revit to do both at the same time. Your have a couple of options as I see it.
1. Use area plans instead of using the rooms to get your areas. You can then place area boundary lines wherever you need them to be.
2. If this is an isolated area you can make all the walls around the stair (including the wall on the bottom of the 'blue' area) non-room bounding and then draw room separation lines on the wall faces to create the boundary as you want it. You may need to split some of the walls on the top portion to get the behavior you are after.
