I want to curve an object to make a path like a roller coaster.

I just made ​​the basic shape (wooden tablet, left and right binary).

How to curve it?

Thank you so much.

Important

Make sure your track model's origin is moved to align exactly on the edge of the model. The modifier will depend on the origin's Position to make duplicate and alignment.

enter image description here

  1. Use the Array modifier to create copies of the track model.
  2. Create a bezier curve representing the curve and length of track.
  3. Add a Curve Deform Modifier and target the bezier path curve object.

    enter image description here

The blend file ...

Extra Note
Instead of "Fixed Count" use "Fit Curve" on the array modifier Fit type drop down menu to improve control to the duplication of the mesh according to the length of the curve.

    $\begingroup$ In the Array modifier enable Merge so you get smooth surface everywhere and you don't have artifacts where the tiles meet! $\endgroup$ – Jaroslav Jerryno Novotny Jan 26 '16 at 14:16
