(MDI) Certified Mechanical Design Technician (CMDT) CMDT assessments center on real-world mechanical design tasks analyzing load paths, selecting appropriate fasteners, interpreting GD&T callouts, and troubleshooting assembly interference problems. You’ll work with actual CAD files and tolerance stack-up calculations, not theory. Technicians who excel know how materials behave under stress and can catch design flaws before fabrication begins.
