About Course

This course introduces learners to Computer-Aided Design (CAD) as the foundation of modern engineering and digital fabrication. Through structured online lessons, students will learn core design principles, 2D drafting, and 3D modeling using industry-standard CAD tools.

The physical sessions focus on translating digital designs into real-world components, preparing files for manufacturing, and understanding design constraints based on machines and materials. By the end of the course, learners will confidently design parts ready for 3D printing, laser cutting, and CNC machining.

Module 2: CAD Software Interface & Design Environment
Learners become familiar with the CAD software interface, navigation tools, workspaces, and basic settings. This module builds confidence in moving, viewing, and managing design files efficiently.

Module 3: 2D Sketching & Technical Drawing Fundamentals
This module covers 2D sketching techniques, geometric constraints, dimensions, and technical drawing standards. Learners practice creating accurate sketches that serve as the foundation for 3D models.

Module 4: 3D Modeling & Solid Design
Learners transition from 2D sketches to 3D models using extrusion, revolution, fillets, and other solid modeling tools. Emphasis is placed on creating clean, manufacturable designs.

Module 5: Parametric Design & Design Intent
This module introduces parametric modeling, teaching learners how to create flexible designs that can be easily modified. Students learn how design intent improves efficiency and reduces errors in manufacturing.

Module 6: Assemblies & Component Design
Learners explore how to design individual parts and assemble them into complete systems. This module covers mating components, checking fit, and understanding tolerances in digital assemblies.

Module 7: Design for Manufacturing (DFM) Principles
This module focuses on designing parts specifically for manufacturing processes. Learners study material selection, tolerances, wall thickness, and design limitations for 3D printing, laser cutting, and CNC machining.

Module 8: Preparing CAD Files for Digital Fabrication
Learners learn how to export and prepare files for different machines, including STL, DXF, and STEP formats. The module explains file optimization, scaling, and common errors before production.

Module 9: Practical Workshop – From Design to Machine
This hands-on module connects digital design to physical production. Learners bring their CAD models into the workshop and prepare them for fabrication using real machines under supervision.

Module 10: Capstone Project – Digital Design to Physical Prototype
In the final project, learners design a complete component or product and manufacture it using appropriate machines. This module reinforces real-world problem-solving and practical application of CAD skills.
