I'm giving a presentation at a SolidWorks summit tomorrow and was wondering if you guys have that one thing you go to to get that "ah ha" moment from the crowd. I'm presenting on Hotkeys/shortcuts/macros - How I do things faster, so anything that would fit in with that would be nice. A simple example would be to highlight two parts in an assembly and select the 2nd tab on the feature manager tree to see their mates with the common mates in bold. I have been on SolidWorks since 2005 and just picked this up at SWW2012. I got a good smile out of that and it has saved me so much time from serching for a specific mate.
