I think what might be useful for this sort of thing would be a medial-axis carving option that lets the user just manually set a fixed max-depth where the cutpaths don't vary in depth based on the width of the form and the cutter shape - like in the case with V-carving/B-carving. Instead, the cutter follows the medial-axis as with V/B-carving but just treats it like the profiling operation, where the user can toggle between varying cut Z to retain the shape of the form being carved, or if they just want a cutter to follow the medial-axis and specify a maximum radius/distance from the edges of a shape to allow it to travel - which currently is determined by the radius of the cutter itself. Hrmm, just thinking out loud. It would effectively allow the medial-axis carving operation to function like a profiling-along-centerline of the canvas' shapes and forms.
