I have been trying to figure this out for a long time now but I dont know what I've done wrong or how to correct it. Essentially, I have made this object and when finished, went to move the objects origin. Went into object mode, selected the object and hit Centre New. Phoooof!!!! It disappears completely, no sign of it Nada.... No mesh, No Data, No Origin, Nothing. Tried checking other layers, duplicating, moving, copying, exporting/importing in different formats checking for stray verts etc., decimating the mesh to the extent of it becoming unrecogniseable. Still happens. I've reached the end of my expertise (which isn't extensive). Any ideas? I really don't want to remake the mesh again unless absolutely necessary. I have a .blend file if you want to see what I mean. Thanks in advance.
