Computer Aided Three-Dimensional Interactive Application (CATIA) is a CAD program that was originally developed for aircraft and vehicles and has established itself and in engineering and in the consumer goods industry, the I-DEAS and Unigraphics as standard software. The application package is currently leading CAD software in this area, it was developed by Dassault Systemes and distributed on IBM. CATIA V5, the fifth and the latest version of the software released (1999) offers scalability and leading-edge technology and is therefore suitable to the needs of small and medium-sized industrial enterprises and the needs of large companies in all industries cut. Compared to the previous version CATIA V4 many new features are added, were already existing functions have been enhanced significantly. CATIA V5 has workbenches for various technical applications, eg for the creation of product data, the development of three-dimensional models and the derivation of two-dimensional drawings of these. Before particularly in the CATIA V5 is often used because it has powerful tools for work has to be used mainly in the interiors and in the body development.

In addition to the design can use the software but also for various other applications, it supports the engineer in all phases of the product life cycle. For the professional life of engineers and technicians, especially in engineering, working with complex CAD and CAE software such as CATIA is becoming increasingly important. CATIA V5 running on Windows is to use than previous versions much easier for the user interface is much clearer. Due to the more complex matter started is still not always easy. A professionally carried out CATIA training can, therefore, both for companies that want to use CATIA in the production process and make for job seekers technicians and engineers paid off handsomely.
