Co z Parametric Solid Modeling?

Parametric solid modeling is a designan approach in thee geometrie of a 3D model is governed by a set of parameters andtheir relationships. These parameters can be numeryc (e.g., width, height, angle), logical (e.g., if- then conditions), or derived frem external data sources such as weather files officancy schedules.
