![]() It is often compared to working with modeling clay. What Is Direct Modeling?ĭirect modeling empowers you to define and capture geometry quickly, without spending time worrying about features, constraints, and original design intent. Parametric modeling is an approach to 3D CAD in which you capture design intent using features and constraints, and this allows users to automate repetitive changes, such as those found in families of product parts. ![]() Read on to learn more about both methodologies to determine which is right for the work you do. Some like the freedom and flexibility of direct modeling, while others prefer the feature definition and dimension control capabilities associated with parametric systems. 2022.Įngineers have long debated the virtues of direct vs. Editor's Note: This post was originally published in 2017, it was updated in Dec.
