Unrolling Command with Bend Callouts

Hey guys there seams to be new plug-ins and updates all the time, and one function i am still looking for is like other CAD programs with sheet metal design when flattening a part it can give you the centerline of the bend with the callout of radius and degree of bend. Has anyone seem a plugin for Rhino that will give this function. It would a great tool to add in the next version of Rhino.
