Faces on meshes disappeared; can't revert them back

Hi all,

I have this problem:

Basically, even though I enabled the solid view mode, most objects in this scene get displayed in wireframe mode. What’s more puzzling is that they don’t get rendered, only solid objects (just very few) do. Since in the past days I’ve had an object randomly (without my intervention) scaling itself to zero, I’m wondering if for some reason (bug?) my .blend file got corrupted and now is giving all sorts of problems. Of course, all objects are set to renderable. I’m using Blender Internal.

Any suggestion?

EDIT: I just noticed that the only items displayed are curves, and that the console is reporting the following errors:

did you extrude edges only and then delete the inverse selection’s faces?

By doing that some faces get extruded, but that’s all, results aren’t correct and then even if it worked I would have to do that for every single object in my scene. That wouldn’t resolve this problem.

Here’s a .blend file containing an object affected by this problem, anyway:

error01.blend (665 KB)

Did you model this in blender or import it from another program.
The model you linked to is just edges, no faces so cannot show as solid. You either you deleted them or an issue with an import.

No, I modeled this scene completely in Blender. I just noticed that the problem is that all faces from meshed disappared as you say and I changed the thread title accordingly. I don’t remember doing anything that could have caused this either (ie: haven’t deleted them. Is it even possible to do this on all objects at once, anyway?). However, I suspect it might be Cycles’ fault, since I was experimenting with that and when I reloaded the file after closing Blender, it showed objects in this way.

Big annoyance :spin:

Here’s the full scene, hopefully it can be fixed in some way.
I’m posting this also because the file I previously posted doesn’t report the errors this does:

staffa.zip (272 KB)

it’s important…anyone help his…thanks

It’s blender’s 2.61 version. have you worked in a different version too on this file?
I would recommend using newer version. There’s a bit 'more skinned version. Hope with some Alt-d and bit more added faces it’ll be back
Happy blending!

Same here, 2.63!

Reinstall fixed it for me.
