# How to bend one side of a planar mesh fade the bending effect towards the other side

I couldn't figure out how to bend one side of a planar mesh like the edges on that side follow a circle. I also want this bending effect to fade smoothly towards the other edge. It is like square(projected) piece cut out from a sphere but I want to control the fading effect and I also want one side of the piece to be a line. I thought, this is a primitive thing, it cannot be considered as "do the modeling for me" request. I'm sorry, If I'm not in the right place to ask such a question. I tried different modifiers but I couldn't converge to what I was willing to see. What is the easiest way of doing this in blender?

Edit: I tried to sketch it: In this sketch, side view shows that from B to C it is bended. This is the final thing that I want to model. Then, I will repeat this round a cylinder. That part is easy. But, initially, I have to figure out how to bend one side of the mesh from B to C like in the first figure. The edges connected to the corner A are just lines. And the shape is symmetrical.

• If you could add a few pictures of the effect you're looking for that would help a lot. At the minute it's a little difficult to understand what you're trying to achieve. Jul 29 '14 at 14:31

• You can have a look at the Warp tool which can be found by searching using the Spacebar menu. I can't really post an answer since I never use it. All I really know is that the 3D cursor position affects how it turns out. Aug 10 '14 at 19:53

Here is how to do it. Doing it with modifiers isn't possible as far as I know. If you need more control, comment.

1. Start by adding a circle.
2. rotate the circle by 90 degrees on the X axis(RX90).
3. Delete the bottom half of it.
4. Take the bottom to vertices and duplicate the by 2 units on the y axis (Shift-DY2).
5. fill the two vertices.
6. hit (Ctrl-R).
7. add 1 less loop cuts then half the number of vertices in your circle you can use the scroll wheel to do this.
8. Join up all the faces (Ctrl-E>Bridge Edgeloops).
