disappeared sections

[Tarkus]

This had not happened to me yet: 36_1_28:
I reopen a drawing made a few weeks ago with various sections and I find myself at this surprise:
The views of the sections are but no longer dissected, they are in fact external views of the part, seen from the same direction that I gave to the section lines.
Yet the section lines are in place and bound to the geometries of the part.
Perhaps some setting has jumped, I have also tried to put/cut the check on the various property modification options section, but nothing changes, even making new sections on the part, makes me a view from the outside and not along a section line.
the trouble is almost certainly in the side file, because if I try to put it in a new table it is not possible however to dissect it.
Yet in the .ipt file, on document->modeling settings, the participation option in the section has checked.
I don't know where else to see
Any ideas?

help.
I add the .ipt file.
Maybe someone wants to try to put it on the table and make sections, so I can figure out whether it's the .ipt file or what's wrong.
Thank you in advance.

I don't know.

high tests:
-I do a "save with the name of the file "bastardo"= nothing to do, even the copy put on the table does not dissect.
I make a new file and we get the file" bastard"= ok, the new file gets dissected.
almost certainly is a setting of the "bastardo" file, but what?

I exhume this old mine because I had to do pdfs of the bastard's table, but I didn't want to remake all the sections.
So I put myself to try them all to see to awaken the "sectionable" of that file.
I came up with the great idea of making an extra extrusion to see if at least that was dissectable.
Bingo!:4406:
It's just a trivial extrusion on a face and the file regained the sezionability on the table.
even by eliminating the extrusion, the file is "cured".
As far as I know it is a problem that only happened to me, but you never know, better put it to acts:36_1_11:
