There are two basic ways to use parametric variables:
Link parametric variables to properties of custom component objects to change the properties in the custom component dialog box. For example, you can change the object’s name, material and profile.
Use parametric variables for calculating values. For example, you can calculate the position of a stiffener relative to the beam length.
You can decide which parametric variables are shown in the custom component dialog box. Hide the parametric variables that you use only in calculations and show the variables that you can use for changing the properties of the custom component.
