I've been meaning to create this tool for quite some time now. Inspired by Blender's 'ToSphere' function. Maya lacks by default many tools that could be handy, I really did like this function within Blender, so I figured that I'd attempt to create something similar for Maya. This is also the first tool I've written using pymel, it's definitely a much easier language. It has many useful features as shown in the video. Averaging the selection of objects or components or in conjunction with each other. Converting Quadrilaterals to spheres in seconds. Can perform this task in normal space and object space. Options for flattening the selection for a straighter result. It's very easy to use, and quite handy.
I'll send you straight back the files and instructions/documentation.
