Hi,

I was working on a file that I have to present for an exam next week and I just wanted to verificate something inside by creating a section line. But the section line was not showing, so I thought "there is a problem with the file, let's close it and reopen it". Of course, I saved the file before closing it and when I reopened it, it was like if the section that wasn't showing before had happened and so I lost half of my building. 

I do have a copy of it somewhere else, but I had already made a presentation for the exam on a layout with prospective views that took me quite a lot of time to deal with, and now of course they also are sectioned. I tried to copy paste the copy of the building I had at the exact same place, but it appears also sectioned, as if the section line was there, but I don't see it, neither can delete it. 

So I was wondering if someone could help me with that file, maybe be able to delete this invisible section line so I could have my building back again on my presentation page  

I uploaded my file so you can check it out.

Thank you so much, 

Frédérique
