Section line weight

[Bling Keeta]

All of a sudden my section line weight becomes super thick without me doing anything to it, and I could not set it back to a thin line.

Ben,

It looks like the Storey Line that is very thick in the Section View? Is this correct?

Cheers,

Yes Gerald, it's the story line. But it's not editable or deleted, and I set the story line thin. It appears when I toggle true line weight so it must be a line tool.
So I don't know where this thick red line comes from.

Is that in a "Live Section" or a Detail view? Not that I know what this could be. Very strange. Might be one of those things you have to send the file to "Support"
