Thank you again for all your answers.
Autocad, I think I've mastered it enough, because after I started skateboarding, I switched to CAD about 18 years ago.
Normally, I also have to meet a person from the employment centre, as part of the CSP, who should allow me to choose a career path.
Lately, in the company where I worked (for 15 years, and) especially the last few years, I managed the file from the preliminary project to the detailed plans (and also the follow-up of fab. ). The CAD and SolidEdge suited me quite well (even the V19). As an "old designer", and a lot of self-training, I still have a little trouble taking the step of direct creation in CAD. Having followed and participated in a few challenges, I feel my delay when I discover the presentations of other competitors and especially the times spent, and displayed (of Greg, Benoit.LF, Bart, franck.barraud, sbrousse or flegendre, among others for example).
Today, I'm thinking of continuing my self-training on SEdge, at home, as well as on SolidWorks (which seems similar) with my PC (hoping it holds up). And find me a Catia or Creo training with maybe an internship to manipulate.
@PL, I agree that it is not very good to have too many similar strings on the same bow, but my wish would be to follow, to find a certain continuity, without taking the wrong path.
Flegendre, thank you for the contact, I have already had contact with them previously.
In any case, thank you again to all of you, for your encouragement.
