Foundation 3D Modeling and CAD Design
Description
Comprehensive introduction to computer-aided design (CAD) and 3D modeling principles using industry-standard software platforms.
Learning Objectives
Students will master fundamental 3D modeling concepts, develop proficiency in parametric and direct modeling techniques, create complex assemblies and technical drawings, understand design principles and constraints, and gain expertise in multiple CAD software platforms including Fusion 360, SolidWorks, and open-source alternatives like Blender.
Topics (12)
Overview of 3D modeling history, CAD vs traditional drafting, coordinate systems, geometric primitives, and industry applications across automotive, aerospace, architecture, and consumer products.
NURBS fundamentals, surface creation techniques, boundary surfaces, swept surfaces, surface continuity, surface analysis tools, and hybrid solid-surface modeling.
Rendering engines, lighting setups, material properties, texture mapping, camera settings, composition principles, and post-processing workflows for professional visualization.
Hands-on training with Fusion 360, SolidWorks, and Blender interfaces, viewport navigation, selection methods, display modes, and workspace customization for optimal workflow.
Sketching tools, geometric relationships, dimensional constraints, construction lines, sketch patterns, and best practices for creating fully defined, robust sketch profiles.
Parametric feature creation, extrude and cut operations, revolve features, sweep and loft techniques, fillet and chamfer operations, Boolean modeling, and feature dependencies.
Feature trees, parametric relationships, design tables, configurations, global variables, equations, and feature suppression techniques for flexible design workflows.
