Why can't I create a pipe from this curve? I have created a bezier curve and small circle. I want that circle take the shape of bezier curve so that the curve becomes a pipe. In the gif you will notice that its becoming flat, not like a pipe.
What is wrong with my settings?
Blend file
For this setup to work, your circle has to lay flat on Z axis.Like this:


And it has to have this rotation applied, so you can rotate it in object mode and press Ctrl+A and choose Rotation or rotate it in edit mode. It will have exactly the same effect.
