Highlighted Lines Overlap - Lines may not form a closed loop Error.

Hi,

I am seeking some help with warnings in Revit.

The file I am working in is a very large file at 500mb (with links) so I am working through clearing out the warnings as it is now impacting a colleagues machine. 

We have a large amount of these warnings in the model, but the issue I am having is it doesn't allow me to hit 'show' and even when I search by ID nothing actually shows on the screen. As you can see it tells me the line category is '<Area Boundary>' and it is a Model Lines but I can't seem to find a single line of this type within our model.

Any help/advice would be very much appreciated.

Open up a default 3D view.

Draw one line using that style.

Select it, right click and select all in project.

You should be able to determine their locations at this point.

Caveat; I haven't used Area Boudnaries, so there may be something about them that could make this more difficult.

No luck, thanks for the suggestion though.
