smooth edges.

hello, all.
I have a question in the picture under this you see the edges of the thing i’ve made.
I want smooth edges but the subdivision surface won’t work well because then the object will deform…
How can i only make smooth edges?

Thank for helping already…

since the shape is basically made out of circles you can use the ‘to sphere’ function(Alt + Shift + s). If you don’t have enough vertices to make the shape smoother, subdivide it first.

Another way would be to start over and make the shape with curves.

Also, keep in mind that you only need to make one third of the shape, then you can just duplicate for the rest. This will ensure that the model is symmetrical.

Ok, ty i will look tomorrow on it but thank you for reply…

Curves would be the best method as mentioned above.
