Creation of a stiffness between 2 pieces in 3 directions

Hello

 

I want to create a stiffness between 2 points of a part and apply different values in the 3 directions. Could you tell me how to create these stiffnesses, is it when using solidworks when creating the assembly or when creating static analysis

Hello

We have to do that in Motion.
