Here's a situation I ran into this evening, which is a very good example of when to use the "select similar" function in the Graphite Tools.

I have a model where I need to select many circular sets of polygons on the surface.  Some of these polygons are perfectly round, while many others were not.  I needed to select all the polygons that weren't perfectly round, so I could make them so.  The difference between the few perfectly round ones, and the not-so-round ones, was very minimal.  Just a matter of a slight vertex position difference.

In this image, I have all the polygons I need to select indicated by Green arrows.  I do not want to select the ones that are already perfectly round, indicated by the Red arrows.

Since each set of polygons contains 4 quads, selecting them according to number of sides wouldn't be efficient.  I could do that, and then just DE-select the few round ones I don't need, but there's a better way.
