When 3D modeling is based on parameters, your model won’t deviate from the parameters such as dimensions or curvature, and constraints that you set. Pros and Cons of Parametric Modeling Pros Accurate This has several benefits, including high accuracy and efficiency, and parametric modeling software is widely used in fields like mechanical design engineering. These define the nature of objects as well as how objects relate to each other. Parametric modeling is a form of 3D modeling in which models are built upon pre-programmed rules or algorithms known as parameters.
