I can't seem to wrap my head around on how to make a cricle from a square in a nondestructive way.

The result I'm trying to achieve is this: enter image description here

Starting from this:

enter image description here

I've tried inserting a face but it won't let me slide it anywhere from it's starting point. I've also tried extruding and then scaling it in but the shading gets all weird. I just want to add the extra edges and make it more like a circle.

Any help would be appricated!

Inset the faces with I, then use To Sphere tool (Shift+Alt+S,1) to make the edge loops round.

Next enable the proportional editing (with a Sphere falloff type) and transform the middle vertex upwards (G,Z). Finally extrude the four middle faces upwards (E,Z). enter image description here


Spin a subdivided section around its vertex and deform the result if you like.

Ok, here you are

  1. Ađd a plane
  2. Delete its three edges
  3. Subdivide the remaining edge as many times as you want
  4. Put the 3D cursor at one end of this edge
  5. Select all and spin the edge with 3D cursor as your pivot
