What is the function of the "Parameter" in Fusion 360?

In Fusion 360, the function of a "Parameter" is primarily to define variables that control dimensions and features within a design. This allows for greater flexibility and efficiency in modeling. By establishing parameters, users can modify dimensions dynamically, and when a parameter's value is changed, all dependent dimensions and features will automatically update to reflect that change. This is particularly useful for creating designs that require varying sizes or for making iterative changes without needing to manually adjust individual dimensions throughout the model.

Parameters can be used to control a wide range of aspects in a design, such as the height of a feature, the radius of a curve, or even more complex relationships involving multiple features. This level of control enhances design automation and helps streamline workflows, making modifications easier and designs more manageable.

While the other options mention important functionalities within Fusion 360, they do not accurately capture the specific role that parameters play in the parametric modeling framework, which centers around controlling dimensional and relational aspects of the design.
