where i can get blueprints and detailed assembly drawings for designing ?
i need more detailed drawings of assemblies and blueprints of cars and bikes having unique concept designs.
For practice with CATIA or any CAD system, just take measurements off of the real, physical parts. Bicycle frame, handlebars, fork, seat, etc. would be great shapes to learn from. Same with car parts. Besides working on your CAD skills, try to improve on the design of the parts to develop your engineering skills.
