Room boundary

[Anonymous]

Hi All

Having some issues with room boundaries... They keep going to the wall centreline rather than the internal face.

Rooms have always worked perfectly fine until this project. It was originally created in a newer version of Revit to what the client required, So we exported as IFC, then imported the model into an older version of Revit. I've then swapped some of the families, walls, floors etc for the correct revit models so they are no longer IFC and this seems to be where the issue has come from. 

I've tried a few things people have mentioned online but nothing is working. The walls are all room bounding.
Unfortunately the job is on an NDA so I cannot upload it

Thanks in advance

Josh

Can you duplicate the issue in another project model. Create a generic model, export it to IFC and import it into an older version. see if you have the same issue. if you do, then you can post the generic model and IFC for us to look at. 

if you draw 4 walls in your current model using the walls tool, do you have the same room boundary issue?

you can also try this....

HI @hmunsell 

Thanks for the suggestions, unfortunately I'm not having any luck trying to duplicate the problem. 

I have drawn 4 new walls and created a room in the same project and the same thing happens. I have also swapped the walls for some of the standard Revit library walls and still the same thing

I've checked the area and volume computations as you suggest and they are already on the correct settings 

Thanks,

Josh

just share part of it, not the whole projects so we can check? thanks

Hi Guys

I have attached a stripped out version. It appears to be the room colour fill is overflowing into the centre of the walls, while the wall boundaries are actually where they are supposed to be

Thanks

i noticed in my Areas and Volumes screen capture I provided the "At Wall Center" highlighted. that is the selection that seemed to duplicate the issue you described. The correct setting should be set to At Wall Finish. just wanted to clarify that 😊.

It is neither the rooms/room calculation nor the room boundaries...You are using wireframe mode. Either switch to hidden lines or refresh the Color scheme location which will force hidden lines

interesting...... if you cut a section the room room boundary appears at the interior face of the wall.

That worked! thank you so much. Must be a glitch with Revit not registering it being set to background?

the above comment from hmunsell might make the behavior seem like a glitch but it is not a glitch

the finish face is only relevant for the area and volume calculation. The room boundary is the center line of the wall, hence the Color Fill always covers up till the Wall center line; otherwise at the Doors you would be ending up with a gap.

• Changing to hidden line or shaded or any other visual style other than Wireframe would hide the fill which is under the wall.
• What Refreshing Color Scheme Location does is that it forces the Hidden Line mode
