It is a fact that computer-aided design and manufacturing software, and technologies in the field of manufacturing, are advancing and seeking to be increasingly complete, tending towards collaborative, multidisciplinary and intuitive platforms. This type of platform offers the user the ability to define a complete manufacturing system in which to include more and more stages from different areas, being able to observe the interrelation of all of them and the consequences that the modification of one element may have on the others. Finally, being able to extract a series of analyzes of the system, in search of an optimized process with which to save time, resources and therefore generate the maximum possible benefits. Currently, 3DExperience has become the maximum reference for this type of platform, being capable of offering almost unlimited possibilities. This work will show the technological leap between the Catia V5 (Computer-Aided Three-dimensional Interactive Application) software and 3DExperience platform. The main improvements and innovations that the 3DExperience platform brings are briefly presented before addressing the implemented case study. Defining and simulating the industrial digital model for the assembly of the Garret TPE 331-10R turboprop engine on the 3DExperience platform is very instructive due to its ease of visualization and the management of the complex process through concurrent engineering, which involves the assembly of an aeronautical engine, offering process simulations of high academic and industrial value.
