Overview for beginners of CATIA switching from other CAD software

We used CATIA for quick prototyping of the products. Since, the utility trucks are customized according to the customer need, modifications and changes to the basic or existing designs are significant. CATIA helps in the process for modification and generating body trucks easier. Being in the product design and development department required us to keep modifying the existing designs. With CATIA, there was no need to delete the modifying part. Multiple drag points of the original design provides a mesh like design, where not only simple geometry but complex geometries were equivalently easier to modify.
It becomes tedious when making modifications in a large scale assembly parts. However, CATIA made it easier to handle. Different applications of our products require constant modifications to the utility designs. I used to relocate interference of hydraulic hoses of boom assembly, boom bucket modifications, and body modifications of the truck.
One issue I faced is the learning curve of the software. Having many modules requires one to invest time initially. However, once learned it becomes really handy in the industry.
