Drawing Sheet: Can't Break a Section-View Although I Was Doing It Just Yesterday

[Anonymous]

Hi.
Yesterday I was breaking the sectio views and no problem was happening at all. Today after opening the drawing sheet (it was saved as DWG) in inventor it now does not break any section views; whenever I hover over section views to break them nothing happens and I can't select them to start breaking. Help please.

I deleted the views I was working on and made new section views and it worked.
