Quick (stupid) question. Just upgraded from 2010 to 2015. I have my default scene set to "plain white". I noticed that when I turn my part around, the holes that are in it appear to go all the way thru part when looking from the bottom up, but when looking from top down they appear "solid" and not going all the way thru part. I don't recall ever having this type of view before. What am I missing? I probably changed a color setting somewhere unknowingly during my SW setup at install time. Not a problem, just an annoyance. I've attached the part. Thanks in advance.
