Hi Brian, it doesn't particularly have any effect on regular rendering.

But if you wanted to use polygon modeling tools to do some further editing of the model in the polygon environment, then of course it is nice to have the polygons as well organized and structured as possible.

There are also some other cases where it can make a difference, like you may want to do some special rendering effects where you actually display the wireframe to get a kind of technical design look.
