CAD-A-THON 2026 is a time-bound CAD design and engineering challenge focused on aerodynamic design and real-world feasibility. Participants will design, analyze, and optimize solutions under defined constraints, simulating a real-world engineering workflow. The event emphasizes design efficiency, engineering validation, and manufacturability, pushing participants to think beyond just modelling. The competition culminates in a final stage where the top 5 teams bring their designs to life through 3D printing and testing, bridging the gap between digital modelling and physical validation.

Competition Structure
Round 1: CAD Design & Modelling Participants will: • Create parts/assemblies addressing the problem • Focus on design efficiency and simplicity • Use parametric and constraint-based modelling Evaluated on: • Fewer features and components • Clean modelling practices • Effective use of symmetry and parametric design
Round 2: Analysis & Validation Participants will validate their design using: • Stress / motion / performance-based analysis • Logical engineering justification Evaluated on: • Correct analysis setup • Design improvements after validation • Accuracy and reasoning
Round 3: Feasibility Pitch Participants will: • Present their design concept • Justify feasibility • Explain design decisions Evaluated on: • Cost, weight, and material optimization • Manufacturability • Clarity of explanation
Evaluation Criteria
Preliminary Round • CAD efficiency and feature optimization • Engineering feasibility and validation • Aerodynamic performance and design logic • Manufacturability and optimization • Clarity of explanation
Final Round (Key Highlight)
