Parametric design is a design method in which features, such as building elements and engineering components, are shaped based on algorithmic processes rather than direct manipulation. In this approach, parameters and rules establish the relationship between design intent and design response.
Parametric models are contrasted with the semi-parametric, semi-nonparametric, and non-parametric models, all of which consist of an infinite set of "parameters" for description. The distinction between these four classes is as follows: [citation needed] in a "parametric" model all the parameters are in finite-dimensional parameter spaces;

The software combines direct modeling with dimension driven design (features and synchronously solving parametrics) under the name "Synchronous Technology". [3] Parametric relationships can be applied directly to the solid features without having to depend on 2D sketch geometry, and common parametric relationships are applied automatically.
Parametric modeling is very powerful, but requires more skill in model creation. A complicated model for an injection molded part may have a thousand features, and modifying an early feature may cause later features to fail. Skillfully created parametric models are easier to maintain and modify. Parametric modeling also lends itself to data re-use.
The ex-CoCreate CAD Products are now owned by PTC and offered as "Creo Elements/Direct Drafting" and Creo Elements/Direct Modeling". Creo Parametric is an application of a suite of 10 that provide collaborative solid modeling, assembly modeling, 2D orthographic views, finite element analysis, parametric modeling, sub-divisional and NURBS ...
PTC Inc. (formerly Parametric Technology Corporation) is an American computer software and services company founded in 1985 and headquartered in Boston, Massachusetts.The company was a pioneer in parametric, associative feature-based, solid computer-aided design (CAD) modeling software in 1988, including an Internet-based product for Product Lifecycle Management (PLM) in 1998.
