Project Based Computer Aided Design from an Industry Perspective
2Computer Aided Design
DEFINITIONComputer Aided Design (CAD) involves creating of 3D computer models of parts and systems defined by geometrical and material parameters. (Inc., 2021)
WHY CAD ?-Representation of systems and products in 3D space-Simulation of system/product performance in real-world conditions
ENGINEERING APPLICATIONS (MECHANICAL, CIVIL & ELECTRICAL)-Product/system Design-System/Product performance simulation-Product development and implementation -Product/system optimization

Product Development Process
1• Product Specification(customer requirements, benchmarking, materials specification, dimensions,
design objectives)
2• Project Costing (BOM, cost of materials, labour costing, supplier identification)
3• Numerical Analysis (hand calculations, engineering equations and principles)
4• Concept Design (hand drawn or computer generated)
5• CAD Model Generation and Rendering (solid edge, Solidworks, Catia, Keyshot, Photoview 360, etc)
6• Design Validation (CAE Methods, system performance simulations, set targets and constraints)
7• Engineering/production drawings (dimensions, standard views, annotations notes,
8• Project Implementation (in-house or contracted)
9• Project Deployment (collect feed back on product performance)
10• Product/system optimization (using collected performance data with set constraints & objectives)
