My linear pattern is not showing, and is not snapping to reference points. It is a similar problem to the linked page, but i am using sw2015. Actually, pattern is sometimes working and other times not. I do not see any reason that keeps the pattern feature from working, and when patterning does work, I cannot tell if anything different was done that allows it to work.

Also, snapping to nearby points on drawings sometimes does not work with patterned drawings (points for hole wizard) on my SW2015. I do not see any reason for this occurrence, but i suppose a workaround would be to start a new drawing layer instead of using one layer for multiple patterned drawings. This is a minor problem because it is only a time wasting nuisance.
