# Parameters - Lesson 5

Ansys Discovery offers powerful capabilities for creating parametric models. Scripting any workflow involving parametric model requires understanding of how to access geometry parameters and modify the parameter values. Additionally, variables used in scripts can be converted into parameters and saved to Parameter Groups in Ansys Discovery. This allows users with the ability to modify the values of script parameters without editing the script.

This lesson focuses on the scripting commands associated with handling geometry parameters and script parameters. It also includes 2 workshops to get hands-on experience with these commands.

The following topics are covered in this lesson:

• How to access Groups
• How to get and modify the value of a driving dimension
• Script Parameters
• Units of Parameters
