📌 What is Parametric Modeling

• Parametric modeling refers to ability to create 3D models that are driven by parameters or dimensions.
• Designers can create parts and assemblies that can be easily modified by changing parameter values.
• This makes it easier to make design changes and to create new projects with variations.

📌 What are the advantages of Parametric modeling?

• Parametric modeling ensures that all features in model are interconnected, so changes made to one feature will automatically update all other affected features thus making model accurate and consistent.
• Parametric modeling significantly saves time, cost of prototyping and testing.
• Parametric modeling makes it easier to collaborate with other designers & engineers by providing clear and accurate representation of important parameters.

📌 How to convert the existing traditional CATIA Cad model into Parametric Model

In 3DEXPERIENCE, you will need following Apps  

• Part Design
• Assembly Design
• Engineering Rules Capture

Here we are demonstrating parametric modeling for Connecting rod assembly.

📌 The following video demonstrates traditional CAD Model creation:

• Modelling the upper and lower parts of connecting rod in part design.
• Creating relations within part design.
• Use of assembly constraints.

📌 The following video demonstrates:

• Creating Knowledgeware Parameters in assembly.
• Creating parametric relations within the connecting rod model and knowledge-ware parameters.
• Once knowledge-ware parameters are defined, whole assembly configuration can be driven by changing these knoweldgeware parameters to create various design alternatives using same base CAD assembly.

📌 The following video demonstrates how the structural mesh associated with the component gets updated by changing the parameters in Parametric CAD model.

• The main advantage of this approach is, there is no need to create a duplicate model as well as mesh for each design change.
