I am sure someone can answer this rather quickly. I have been using solidworks for some time now and never have I ever, until today seen a mate in my assembly with a Star. I am almost positive it has to do with autosized parts from the toolbox because today is the first time I actually used that feature and the star's are only located on mates having to do with the autosized part. I see no ill effect from the star, and don't think is a warning like when it over defined. My coworker has also never seen this and we are both interested in finding out if it's good, bad, or irrelevant. Below is a partial screen shot incase anyone is confused by what I am asking.
