Parametric modeling - demo with PythonOCC

Parametric modeling can be considered as the modeling of objects that can be described using a finite number of parameters or dimensions.

Parametric modeling can also be called as dimension driven modelling.

Parametric modeling enhances the understandability and interchangeability of cad models (cad files) between different cad development platforms

pythonOCC comes with importers/exporters for the most commonly used standard data files format in engineering: STEP (AP203 and AP214), IGES, STL.
