  1. Step 1:

    First, here is the circular pattern.

  2. Step 2:

    I've added a cap to the tube and the a screw to the assembly

  3. Step 3:

    Finally, I'm using the feature driven pattern to place all the other bolts.

    Note that I've used the circular pattern as the driving feature, but I also could have used the counter bored holes also.
