This project report summarizes a student's work in a Computer Aided Design & Drafting lab. It includes 10 experiments where the student drew and modeled various electronic and electrical components, instruments, diagrams and views using AutoCAD software. The experiments covered drawing electronic symbols, components, common instruments, oscilloscope diagrams, TV receiver blocks, radio circuits, power supply layouts, transformer views and loudspeaker views. The final experiment provided hands-on experience using AutoCAD commands to create 2D and 3D shapes for electrical engineering applications.
