Limited Dissolve - All Boundaries option, what does it do?

Hi all,

I am slowly working my way through documenting some options in Blender. I am currently running Blender 2.74 and when using the Limited Dissolve option in the Mesh > Cleanup menu header in the 3D Viewport menu header. Once the Limited Dissolve option is used the Operator Panel displays as follows:


I tried making every different combination of mesh I can think of but am still unable to determine what the All Boundaries option does. So does anyone know specifically what it does, or when you would use it?

As far as I can tell it’s not documented anywhere (did the google thing). It would be great if someone could puzzle it out without me having to poke a dev, as they are super busy with things at the moment :slight_smile:

it fucks up your mesh. never used it, and it has never worked for me :slight_smile: never needed it either.
