To talk about the advantages of parameterization, we must start with modification. The designed parts are not static and need to be optimized and modified according to different needs. So there is a big difference between parameterization and nonparametric. Parameterization is easy to modify, and nonparametric is not easy to adjust.

The greatest contribution of parameterization is to describe the digital model with numbers. The length, width and height of parts, the size of features and the angle between features can all be described by numbers. The advantage of this is that when you need to modify the model, you only need to adjust the parameters inside to refresh the whole model, which reduces unnecessary repetitive work and improves work efficiency.

Parameterization also has function function, which can establish the relationship between dimensions (such as drawing gears), which can not be completed by nonparametric design.

In a word, if you want to use catia to save labor and time, it must be parametric design.

There is not much difference between the two methods if it is only in the learning stage and the goal is to be familiar with commands. Moreover, broken ginseng has fewer errors and is easy to use.
