Terminologies Related to Parametric Modeling

• Parametric Model: Its like a 3D (3-dimenstional) model which has parameters that can be customize according to our requirement. We can easily change the values in the parameter to create change in shape, dimensions and other properties of our model.

• NURBS Model: It is a mathematical approach which is used in CAD and also in computer graphics. We can control its curve or we can say the surface through the use of control points.

• Polygonal Model: Polygonal Model is also known as Mesh Model. It is type of model that is used to create 3D objects by using tiny components. These components or polygons are consist of edges, vertices and faces. Also keep in mind that a single polygon is usually said to be a Face. Though a Polygon Mesh consist of many connected faces (polygon). We can use it to build a 3D polygon model.

• Visual Programming: It allows us to create parametric 2D or 3D models by inserting nodes, setting, changing parameters and connected inputs. It is best for the people who usually don’t have coding skills because it make the user to utilize the power of algorithms with actions and visual objects rather than a script of code.

• Nodes: We can also say it as components. They process and contain a sequence of data about parameters of a model.

• List: It can be defined as a collection of items that can be utilize as a input or output source, managed in a structured way by using indexes which starts from 0.

• Data Types: Each and every item has its own data type. Some items consist of curves, points , some consist of solids and other contains only numbers , it can be vary according to the parametric modeling software.

In this article, we will cover all the necessary detail that is acquired to know about Parametric Modeling. Let’s start with the simple definition, just go through all the points and headings. It will give you a brief intro about what is parametric modeling and why we use it.
