In the past if you wanted center one component on another you often had to resort to reference geometry. You would either design your parts symmetrically about a plane, or create a plane between down the center of the geometry. This wasn't hard to do in SolidWorks, and with the new "Width" plane option its even easier. But why bother when you can use the advanced "Width Mate?" John's latest video shows you how the width mate can allow you to get your parts aligned correctly in SolidWorks even faster.
With the holidays and preparations for SolidWorks World 2011, John took a little break from his weekly video tips. With all that over he's back and this week he's got a nice overview of Mult-Mate.
If you find yourself mating multiple objects to the same references in your assembly you should check out Multi-Mate.
