If Vue blocked on exporting the data to obj, there seems to be a problem with the mesh and Vue's calculus...

I had problems with preceeding versions of Vue, with hollow or other complex objects. Especially, when the thing was mathematically exact, symmetrical, and centered at zero, so many opposed points just differed by the +/- prefix, but not in ciphers. Came up with lacking faces, holes, had points at 32thousand (seems to be some kind of infinity). But mostly, it just ran into a wall and blocked.
Haven't had such problems lately (unchecked "resize and center").

I encounter difficulties when importing complex dxf architecture into Vue. Those I pass over to the free Cinema4d v.CE6, where I can check for errors, and export via 3ds to Vue (ignoring the alert for out-of-date textures).
Up to now, that worked clean and fast, here.
