Introduction to CATIA CAA RADE Customization


In our previous blog post we had discussed on the topic How to learn CATIA CAA RADE Customization? In this month’s blog post we will discuss on getting started with CATIA CAA RADE Customization. CATIA CAA Customization is a rapidly growing niche skill, in CAD & PLM Customization landscape. It is essential for CAD & PLM engineers to learn CATIA CAA Customization skill, as it has very high demand in the market, due to Dassault Systemes’s strategic direction towards integrating 3DEXPERIENCE Platfrom’s core customization around  CAA Technology. CATIA is a widely used CAD system in the market. It provides openness for customization. Let’s discuss below on Getting Started with CATIA CAA Customization

CATIA Knowledgeware Solutions


CATIA offers enterprise know-how automation capabilities using Knowledgeware solutions. CATIA Knowledgeware solutions are namely Knowledgeware Advisor, Knowledgeware Expert, Product Knowledge Template and Business Knowledge Template.

  • Provides CATIA geometry creation, validation and process automation capabilities
  • Minimal coding knowledge is needed for the end user on CATIA Enterprise Knowledge Language (EKL)
  • Enables you to capture and reuse corporate know-how

CATIA Visual Basic Automation


CATIA Visual Basic Automation helps you to use a scripting language to access CAA Automation objects to capture your own know-how and increase your productivity. End Users can customize applications to automate repetitive and time consuming tasks, and to make it fit your own process.

  • CATIA Automation API helps the end user to view the CATIA data model
  • CATIA Macros relying on standard languages across the platforms; MS VBScript on Windows, VB Script provided by Winsoft on UNIX
  • CATIA Macros can be recorded and reused interactively
  • Can integrate with Visual Basic for Application (VBA) or standalone Visual Basic projects
  • Provides Selection capabilities at Feature level and Sub-Element level providing access to Face, edge, vertex

CATIA CAA RADE Customization


CATIA CAA is a de facto standard API written in C++ using tools and methods for an Object Oriented programming environment

  • Interactive software development tools built on top of best-in-class de facto standard RADE tools
  • Uses Microsoft Visual C++ on Windows and Standard C++ Compilers
  • CATIA CAA V5 Addins provides easy to use Wizards to create workbenches, interactive commands, dialog boxes, etc
  • CATIA CAA is a huge set of API covering all the domains
  • CATIA CAA offers single source code working on both WINDOWS and UNIX operating systems

CATIA CAA Paradigm / Application Architecture


CAA is an acronym for Component Application Architecture. CATIA CAA is a comprehensive and open set of APIs to be fully integrated into Dassault Systemes Portfolio. CATIA CAA permits to customize your business application, extending application portfolio with your business knowledge and reusing CATIA CAA Components to build your own solution.



CATIA CAA Workspace


CATIA CAA Workspace or application is made of several frameworks that often referred as components. Each framework can have several modules that can hold source files.

  • Every CATIA CAA Application is a set of 1 to n components called as the frameworks.
  • Each framework is composed by 1 to n modules.

CATIA CAA Workspace: Prerequisites


To access the header file of CATIShaft for build/link time, the customer Application needs the header file complete path : Workspace + framework + module

CATIA CAA Workspace: Directory Structure


CATIA CAA Workspace directory comprises of two perspectives. They are Build Time View and Run Time View respectively.

Build Time View contains all source files, that are necessary for CATIA CAA Workspace such as C++ source files and header files. Additionally it contains file likes text file and Identity Card XML or header files.

Run Time View contains the output binaries, libraries and resource files required for executing CATIA CAA Workspace customization on a CATIA Client Workstation. These files include Dico, CATNls, CATRsc, etc
