Catia Scripting is a powerful tool that allows users to automate tasks and customize their Catia experience. With scripting, you can create macros, write scripts, and develop applications to enhance your design process. In this article, we will explore what Catia Scripting is all about and how it can benefit you.

What is Catia Scripting?

Catia Scripting refers to the process of creating scripts or programs to automate repetitive tasks in Catia. It allows users to write custom code that interacts with the Catia API (Application Programming Interface) and perform various operations within the software.

Why should you use Catia Scripting?

  • Automation: By automating repetitive tasks, you can save time and increase productivity. With scripting, you can perform complex operations with just a few lines of code.
  • Customization: Catia provides a wide range of functionalities, but sometimes you may need specific features or workflows tailored to your needs.

    With scripting, you can customize Catia according to your requirements.

  • Error Reduction: Manual processes are prone to errors. By automating tasks through scripting, you can minimize human errors and ensure consistent results.
  • Efficiency: Scripting allows you to streamline your workflow by eliminating unnecessary steps or combining multiple actions into a single command.

Different ways of scripting in Catia:

1. CATScript:

CATScript is the built-in scripting language provided by Dassault Systèmes for Catia automation. It uses VBScript as its base language and provides access to a vast number of Catia objects and operations.

2. VB.NET and C#:

Catia also supports scripting using .NET languages like VB.NET and C#. With the .NET API, you can leverage the full power of the .NET framework and create advanced applications that interact with Catia.


CATVBA (Catia Visual Basic for Applications) is another scripting option in Catia. It is based on Microsoft’s VBA language and allows users to automate tasks using a familiar programming environment.

Getting started with Catia Scripting:

To start scripting in Catia, follow these steps:

  1. Enable Scripting: In Catia, go to Tools > Options > Infrastructure > Part Infrastructure. Enable “Allow execution of macros” and “Allow execution of scripts” options.
  2. Select a scripting language: Choose the scripting language you are comfortable with – CATScript, VB.NET, C#, or CATVBA.
  3. Learn the Catia API: Familiarize yourself with the Catia API documentation to understand the available objects, methods, and properties you can use in your scripts.
  4. Start writing code: Open the scripting editor in Catia and begin writing your code.

    Use loops, conditions, variables, and functions to create powerful scripts.

  5. Test and debug: Test your scripts on sample data or parts to ensure they work as expected. Debug any issues that arise during testing.
  6. Create custom menus or toolbars: Once your scripts are working correctly, you can create custom menus or toolbars within Catia to conveniently access them.


Catia Scripting is a valuable tool for automating tasks, customizing workflows, and improving efficiency in Catia. By leveraging the power of scripting, you can save time, reduce errors, and streamline your design process. Whether you choose to use CATScript, VB.NET, C#, or CATVBA, learning Catia Scripting opens up a world of possibilities for enhancing your Catia experience.
