I recently stumbled upon the segmentation feature “Ctrl-B” of Blender, and today I was wondering how to apply it on a cone? Coz the edges are getting duplicated in a parallel way instead of in a radial way. The attachment should tell everything…
In Edge selection mode, select the edges around the top and the bottom
Subdivide then press F6 and set Smoothness to 1
You can increase number of cuts if you need more
You may or not need to straighten (select the edges at top, press S then the axis key and press 0 then do the same for the bottom) the top and bottom after that in case of the smoothness slightly altered them
