Mesh disappears in 3D with marque

[Achille Pavlidis]

I'm facing this very peculiar problem: a large mesh that shows perfectly on 3D when it is selected or when I'm doing a 3d without marquee, suddenly disappears when doing a 3d with a marquee. If I uncheck the option "Trim elements to marquee" the mesh appears correctly again (but entirely). I cannot get a partial 3d view of the mesh.
Any help?

Does it matter where the marquee is - does it include an edge of the mesh or is it entirely in the middle of the mesh?
Or does the shape of the mesh matter - rectangular or polygon?

Actually just thought you may be using a single storey (thin) marquee and the mesh is on a different storey.
Use the all storey (fat) marquee and maybe that will work.

The marquee is thick, it cuts through a portion of the mesh.
I'm posting 2 pictures one with the marquee and one without. Nothing else has changed (layers, renovation etc are all the same)

Does your mesh has any "micro gap" between points?
I've seen weird behavior in this situation.
Try to do an "Open and repair" to check if there is any error.
Hope that helps.

No, it didn't

I actually dragged a copy and it appeared correctly... I just had to re-do all the SEO's...
