1. GLOBAL GROUP OF INSTITUTES-AMRITSAR (AUTONOMOUS) PRESENTATION ON SOFTWARE TRAINING IN CAD & CAM BY : MANBIR SINGH (2130393)

2. ABSTRACT This passage argues that traditional education lacks practical training, leaving graduates unprepared for the fast-paced, globalized industry. It highlights an institute (GGI) that bridges this gap by offering practical programs with mandatory six-month industrial placements. These placements allow students to apply their knowledge in real-world settings, develop essential soft skills, and gain exposure to current technologies and workplace dynamics. My own experience at a hand tool institute confirms the benefits of such training in acquiring practical and job-ready skills.

3. Introduction to CAD and CAM Software Explore the powerful world of Computer-Aided Design (CAD) and Computer-Aided Manufacturing (CAM) software. From creating 2D drawings to designing 3D models, these versatile tools unlock new possibilities for product development and industrial automation.
