7. Selection of“pedagogical” tools • Instructor’s presentation • Training devices • Supports for trainees (CD, student’s guide, …) TRAINING QUALITY AT SNECMA CTC • Training material Process to selectmaintenance tasks Trainingmanual Learning Management System (LMS) Easy tracking. Well, what about the DMU ? Well, what about the DMU ?

8. Snecma DMU Engineeringdepartments Componentsmanufacturers CATIA DMU Training Center DMU Partners Engineeringdepartments Componentsmanufacturers TRAINING QUALITY AT SNECMA CTC • Introduction to the use of Digital Mock-Up (DMU) • DMU : mock-up designed with a Computer Aided Design (CAD) software. Large file size~ 5 to 10 Gb Lighter files (up to ~ 1 Gb)Re-engineering impossible 3DViaComposer  3D courses on 2D supports Snecma Customer Training Center

9. TRAINING QUALITY AT SNECMA CTC • Introduction to the use of Digital Mock-Up (DMU) • We are OEM. Why use a DMU ? • Because !  • To improve graphics and thus learning efficiency • 3D views  better than 2D views • Engine unavailability for new programs • Easy do / undo / re-do changes • Easy update & tracking • Save time / drawings needs.

11. DMU WITHIN SNECMA TRAINING COURSES • Examples Our vocation is not to present beautiful pictures, but to present accurate, efficient and high quality technical information. • In house LMS with graphics and animations made with the DMU software • Demo • 3D animation to explain a maintenance task (outside our LMS) • Oil filter removal

12. DMU WITHIN SNECMA TRAINING COURSES • Mix of different graphic styles

13. DMU WITHIN SNECMA TRAINING COURSES • Pluses • Easy-to-use software even for non-CAD users, • Possible access to numerous input CAD files… if you pay for the licenses ! • DMU components partial download (better than a whole engine DMU), • Quality of high resolution graphics. • Minuses • Difficult to manage large size DMU, • 3D animations are not so easy to create, • Large RAM required (4 Gb for a comfortable use), • Impossible to create new textures. • Pluses / Minuses
