Parametric input allows you to enter the model data and load data in a specific way so they are dependent on certain variables. These variables for length, width, traffic load, and so on, are called parameters. They are set up in a list of parameters.
The parameters can be used in text boxes in formulas to determine a numeric value. You can edit the formulas using Formula Editor. If a parameter is changed in the parameter list, the results of all formulas using this parameter are adapted.
The parameterized input is reasonable for the models where many changes are to be expected. The formulas of the geometry and load entry are stored in the model data. The parameterized input is also suitable for recurring editing of similar models: you can upload a template file and adjust the parameters.
