SOLIDWORKS Simulation 2018 pin connector has been enhanced. Now you can define a pin connector through more than two cylindrical surfaces in one definition. An improved user interface allows the definition of a single pin connector applied to multiple cylindrical faces (maximum ten).
For instance, in 2017 and prior versions, you had to create 4 pin connectors to connect 5 cylindrical faces of a hinge, as shown below:
Now in SOLIDWORKS 2018, you select all coaxial cylindrical surfaces that are attached to the pin in a single selection box. For example, all 5 coaxial cylindrical faces for the same hinge example can be selected at once, as depicted below.
