# How to smooth a cone side without changing its shape?

I'm trying to smooth cone's side like I did for a cylinder using Edge Split and Subdivision Surface.

However, the cone (red one) is changing its shape at the top:

How can I prevent this?

• You could try adding an edge loop very close to the top. – Ezra Apr 14 '17 at 21:04

• I would like to note that I used Simple Deform -> Taper modifier to change the shape of a cylinder. – Skyblade Apr 15 '17 at 10:55
