Parametric CAD modeling

Parametric modelling uses the computer to design objects or systems that model component attributes with real world behaviour. Parametric models use feature-based, solid and surface modelling design tools to manipulate the system attributes. One of the most important features of parametric modelling is that attributes that are interlinked automatically change their features. In other words, parametric modelling allows the designer to define entire classes of shapes, not just specific instances. Before the advent of parametrics, editing the shape was not an easy task for designers. For example, to modify a 3D solid, the designer had to change the length, the breadth and the height. However, with parametric modelling, the designer need only alter one parameter; the other two parameters get adjusted automatically. So, parametric models focus on the steps in creating a shape and parameterize them. This benefits product design engineering services providers a lot.

The Parametric Modelling Process
Parametric models are built from a set of mathematical equations. For parametric models to have any legitimacy, they must be based on real project information. It is the modernity of the information examination techniques and the breadth of the hidden undertaking information which decides the viability of a modelling solution.


These are the benefits offered by 3D parametric modelling over traditional 2D drawings:

Capability to produce flexible designs

3D solid models offer a vast range of ways to view the model

Better product visualization, as you can begin with simple objects with minimal details

Better integration with downstream applications and reduced engineering cycle time

Existing design data can be reused to create new designs

Quick design turnaround, increasing efficiency
