Correct observation. And what is more, this "maximal rotation rect"
remains the same even when you change the polysides property of a
regular polygon, switching from a hexagon to a triangle or to any other
For what purposes may such a feature be "useful"? I think it was not
intended as a useful feature, it just "happened" during the development
of the algorithms for regular polygons.
And again, I believe, it would not cause too much trouble for the
developers of Revolution to define the rect of a regular polygon as a
"minimal visual rect" that will be adapted to its minimal size each time
the angle of a given regular polygon is being changed.
Another additional or parallel solution would be, which I mentioned in
my last post, to make the values of the vertexes of a regular polygon
available and retrievable, and then let the user choose to set the style
of the polygon to "polygon" based on the given points/vertexes.
