SmartMates functionality saves time by allowing you to create commonly-used
mates without using the Mate PropertyManager.
To use the SmartMates
command in SolidWorks 2013 and older version of SolidWorks, you can access it from Move Component
on the Assembly toolbar. In the PropertyManager, under Move, click SmartMates as
do the mates you need to double-click a component and then click a valid mate
partner. As shown below when you double-click the first component it becomes
transparent indicating Smart Mate.
we select the other mating component and the Mate pop-up toolbar appears as
can do the same procedure for the other mate. Double click the first component
and then select the other mating component.
