Automoblox Dimensioned Drawings on Inventor

In this project, I got to the passenger section part. The most challenging part of this process was finding the exact coordinates of the extruded parts of each shape because there was a lot of math involved in order to put it in the right place. The easiest part of this process I would say is extruding the parts or filleting it. My remaining question for Inventor is how to make stars in a more easier way rather than making each line manually, since using the circular option did not work for me.
