I feel like something is just going way over my head here and I'm missing something really trivial. I'm doing a Grant Abbit well tutorial. I created a set of cubes along the x axis to use as the rocks for the well. I added a simple deform modifier. If I set it to bend at the z axis at 45 degrees, it makes a weird fan shape. I did also try making the origin set to an empty and that just swings the fan around.
