Computer Aided Engineering Drawing (CAED) – BCEDK203 Notes & Overview
🧭 What is Computer Aided Engineering Drawing?
Computer Aided Engineering Drawing is the application of computer software to create, modify, and analyze technical drawings. It combines traditional engineering drawing skills with modern digital tools like AutoCAD, SolidWorks, CATIA, and Fusion 360.
Instead of manual drafting, students learn to produce precise, scalable, and editable 2D and 3D representations used in industries ranging from manufacturing to construction.
