Actually Wings 3D's model is not /fully/ volume-aware, because volume is 
really difficult mathematically to handle; instead, it "only" insists on 
objects being topologically "closed" surfaces.

And yes, Wings 3D /does/ enforce this. There is no way whatsoever to get 
it into an inconsistent state from /this/ perspective.

The display engine might not be able to cope though with all possible 
configurations that are valid with regards to this model, which is 
what's causing you problems.


The most common "visual inconsistencies" in Wings 3D, from my 
experience, are polygons folded over one another, and edges of virtually 
zero length.

The latter can easily be eradicated by selecting all short edges and 
collapsing them to points (use a very small value, and visually verify 
afterwards that the points created this way are all where you'd expect some.

As for the former, look out for edges that, when highlighted, seem to 
"span" multiple vertices. They're a bit of a hassle though.
