SYMMETRY text upside down.

Here is what I mean:

  1. Step 1:

    1. Insert a reference axis in the center of your part.

  2. Step 2:

    2. Use the circular pattern tool. Select the axis as the center of rotation, 2 instances at 360 deg. and the extrude feature that forms the letters. In my example I also pattern the cut, ignore it.
    Good luck.
