loft disappeared in 3d...

[emi_973]

It's a weird thing. I designed a floor on the first floor and something strange in the sections and in the split attachment you see, while in the 3d no.
shows me the perimeter when I step with the mouse but does not show it as "full body". What will I have ever messed up? and how do I restore sight?
Thank you in advance.

temporarily off?
clikka on the bulb at the bottom (under the working area/drawing), if so you should contore in red.
in case you highlight it, dx mouse button, command : discover in the view
turn off the bulb
