All model elements from most section views in a given view folder are suddenly not showing in the viewpoint—only the 2D elements drafted/annotated in the viewpoint show. When one turns on all layers, the model elements do show.
Section marker, layer combinations settings, layer combinations themselves, RFO&GOC, have not been modified. One view in that folder has different view settings from the other ones and the problem still appears —so I can't track it down to specific section or view settings, which change among different drawings in the same folder. Other two views in the same folder don't have this problem.
Other folders with other sections, similar settings, are working OK. Everything was working OK for these ones until a couple of hours ago.
(Don't know if related, but noticed it for the first time together with this: story level lines have allways been set not to show in these; when zooming out to show all elements, tiny dashes appear as placeholders for the story level lines, and when hovering over them I get the message to go to section settings if one wants them to show. Because the model has a few 'workshop' stories below grade, the view zooms out a lot, which I don't remember happening before. ).

Anybody understands what may be going on?
