Been following along with a tutorial and I am supposed to mirror this column that I cut in half (vertically) along the Y-axis. However, I have messed with all the available settings and either it mirrors negatively through its base or it completely clips itself. Not sure what's going on. All the object history has been deleted like the tutorial said and this is my second iteration trying to do this.
Below is what it looks like. Changing the direction or Axis position only result in either nothing / clipping itself out.
