I'm trying to use an array modifier on an object such that each copy is rotated 2° about the z-axis from the previous one, and then translated along the x and the z axis.
This is what I started with (the Empty at the origin is used to rotate and translate the object):
This is what happens after I rotate and translate the Empty (pivot point is set to median point) (doesn't matter whether I translate or rotate first, It still turns out like that):
The problem in the diagram above is that the translation on the x-axis does not happen; only the z-axis and the rotation is done right. If the x-axis translation is done correctly, the track should align exactly, like in the diagram below.
This is the effect I want to achieve:
Here is my Blender file, if it helps.
