PRACTICAL CONTENTS
Practical sessions 1,2 & 3. Solid modeling and assemblies. In the first laboratory sessions, the student will learn to generate three-dimensional elements using regular modeling tools.
Practical session 4. Preparation of technical documentation (plans, projects,...). The main objective of this practical session is for the student to learn to use the tools for the production of technical documentation obtained from the models and assemblies made previously.
Practical session 5. Reverse engineering. The key objective of this practical session is for the student to carry out a three-dimensional reconstruction of an object from photographs. The software can be chosen by the student, suggesting the possibility of using: Meshroom, Eyescloud, ReCap Pro and Agisoft Photoscan (or Metashape). The reconstruction will be made from several photographs, since if a single photograph is used, a faithful reconstruction will not be achieved, but an approximation.

Practical sessions 6 & 7. Design and modeling of a Personal Protective Equipment (PPE). The main objective of these practical sessions is to design and develop PPE in operator positions (protective masks, goggles, helmets, ear muffs, etc.) for the prevention and protection against occupational accidents and damage to health. The student must generate the 3D model of the assembled set and its drawings.
