When i add a curve modifier stairs moves from its position. How it works can u explain in detail.How to set correct position from where i have the exact position i have set. Rotation scale and position are all 0,0,1 of stairs and curve. In some cases why we have to move and adjust. Any suggestion or help. Thanks

I want to achieve this way

You can solve this problem by following the steps:

  1. Set the origin of the curve and the stairs to the geometry
  2. Move the stairs downward on the x-axis to where the arrow is
  3. Rotate it on the y-axis to be parallel to the arrow (Do it in the front orthographic view
  4. move it along the x and the z axis repeatedly to find the best fit. Which will give you this:enter image description here

For getting a much more refined curve I added in another nurbs curve and did a lot of tweaking. Added in plane.Modeled it into a stair added in an array modifier and a curve modifier.And finally this is what I got:enter image description here
