Blue interior walls only

[Anonymous]

Hi all,

Can anyone tell me why my walls in Revit are lined in blue? I don't know how they came to be this way. I can see the drawn wall under the blue lines, but I don't know how to get rid of the blue on the interior walls. I also noticed that the vertical walls are completely blue - no black underneath - while the horizontal walls are blue with the black line underneath.

do you have any assign view template set to none in properties or share your file here so we can check. thanks

Does this help?

No. I magnified the wall and got extremely close and when I clicked on the blue line it was a room, so I hid it for now. Still not sure why it happened though.

What @barthbradley meant is to uncheck that Interial Fill box.

I was showing the OP where the blue lines were coming from.
