I was looking at a couple of parts I created about a week ago and just noticed a folder in the feature tree I have not seen in other sheet metal parts.  I looked in the forums and either could not find a similar question or just flat out missed it.  What I would like to know is how I created this folder in the part (in the left hand feature tree), I can not for the life of me, figure out what I did for it to be created.  Both parts were created and use the same sheet metal gauge table, and both parts are created using the same sheet metal part template.
