Use parameters in Design Studies and link them to variables that can be changed with each iteration of an evaluation or optimization design scenario. You can parameterize model dimensions, global variables, and features from Simulation and Motion studies.
Link parameters to input fields to let the parameters drive the numeric value of the associated feature. For example, if you define Force1 as a force parameter, you can link it to a force input field instead of entering a numeric force value. Changing the value of the parameter Force1, automatically changes the force input linked to it.
