They are responsible for the fine-tuning of models, work in close collaboration with the designer and produce models and patterns and accommodate any modifications. They produce or have the model technician produce the prototype. They are specialised in a specific sector (Menswear, Womenswear, Childrenswear, Lingerie, Knitwear, etc.) and a specific area (casualwear, suits, etc.). They sometimes use software to develop 2D or 3D prototypes, given that CAD is becoming increasingly important in this profession.
Have a sharp eye for details and measurements, work quickly as part of a team, know how to use CAD and 3D tools.
