Curve modifier, deformation only on Z axis Hi I want to model a staircase rail. But when I try my curve modifier the ramp don't deform along the curve like a real staircase rail should do, only on the z axis... Is there a way to tell blender to only deform my object on the z axis while still following the curve organic form?

Thanks 

The basic mesh must be straight, then I will  put an array on it and a curve modifier follow my curve, but the curve modifier don't work like that.. 
..  I want it to adapt to the complex  curve, as you can see, deformation are only occurring vertically, the object is not tangent to the curve!! 

Thanks
Array a Z deformed panel

No, the Curve modifier has no option for that yet.

The trick you can go for at the moment is to Shear your panel and set up an array modifer that not only offest on the X axis, but also in the Z of the right amount to build a seamsless mesh.

Luckily stairs usually have steps that are evenly spaced on Z, so the linearity of the height growth imposed by the usage of the Array modifier should not be a problem in this case.

The curve is now defining only the path of the rail on plan:





Note for example that in the picture there the tile is romboid shaped, not squared shaped.
