How can I smoothly extrude a plane or an svg curve into a circular/rounded mesh? if I simply import an svg and extrude it and then add a subdivision surface modifier, it makes a big mess. I need a way to take a flat complex 2D object and extrude bit by bit systematically while changing the diameter of each extrusion (layer apon layer). I would hope it would end up looking like the semicircle in the photo (though using more complex 2D shapes though). I want to make the bottom image into a semicircular mesh to make it look like the top image. enter image description here enter image description here Any advice?

The manual way of doing this would probably be to extrude it up and then use the"Shrink/Fatten" (Alt+S) tool which scales each Vertex/Edge/Face along its normal which should give you something you might be able to work with.

I wouldn't be surprised if there was already a tool or an add-on to do this more or less automatically but sadly I don't know it
