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. enter image description here

  • $\begingroup$ 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. $\endgroup$ – Ray Mairlot Jul 29 '14 at 14:31

  • $\begingroup$ 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. $\endgroup$ – MarcClintDion 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). enter image description here
  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).
  9. add some loop cuts until your faces are about square.
  10. tweak the shape using proportional editing.

Here is another way to model the smooth shape you want.

  1. Add a circle
  2. In edit mode delete the bottom half of it.
  3. Extrude it to make a half cylinder shape. extrude
  4. Add loop cuts for a smother final shape. loop cuts
  5. Select the end edge loop.
  6. Turn Proportional Editing on.
  7. Scale the end edge loop to 0 on the Z axis, adjust the Proportional Editing Influence to include all but the other end of the shape. scale
  8. Again with the same Proportional Editing settings, move the end edge loop down until the bottom is flat. grab
