view construction lines in 3d

[CAROLINA]

Good morning.
I would like to know why from a few days to this part in the 3d view of the building model that is building in revit are visible the lines of intersection of the floors, almost as if the model was seen wireframe (almost transparent). I don't know if it's a graphic card or PC memory problem...
the file weight is 173 mb

Someone can help me
thank you dear

it seems to me that this problem was present with use of files made with 2011 or earlier version, then solved with updates.

Thank you.
if there are latest updates (service pack....) for revit architecture 2013.
if yes, on which site can I download them?

thank you dear
