3D CAD Course
Master 3D CAD from the ground up and build the skills that engineering and manufacturing teams actually hire for. This course takes you from interface basics all the way through advanced surface modeling, assemblies, simulations, and production-ready drawings. Every concept is grounded in real-world design workflows used across mechanical, industrial, and product engineering. If you want to design parts that get built, this is where you start.
What you will learn:
You will learn to navigate a professional 3D CAD environment, create fully constrained 2D sketches, and convert them into precise solid models using core features like extrude, revolve, sweep, and loft. You will build multi-component assemblies with accurate mechanical mates and manage complex part families using configurations and design tables. The course covers engineering drawing creation with proper dimensioning, tolerancing, and GD&T symbols. You will also explore sheet metal design, rendering, finite element analysis, and design for manufacturing principles. By the end, you will have the technical range and portfolio projects to work confidently in a professional CAD environment.

Covers the layout of a typical 3D CAD workspace including menus, toolbars, and viewports. Proficiency here accelerates every later modeling task.
Lesson 2 • Units, Tolerances, and Document Setup
Establishes correct unit systems, precision settings, and document templates before modeling begins. Proper setup prevents costly errors throughout a project.
Lesson 3 • Coordinate Systems and Planes
Explains Cartesian coordinates, origin planes, and reference geometry used to anchor all 3D models. Learners gain spatial reasoning essential for accurate part creation.
Lesson 4 • What Is 3D CAD
Defines 3D CAD, its role in modern design workflows, and how it differs from 2D drafting. Establishes context for all subsequent modeling work.
Chapter 2HideHide detailsSee details2D Sketch Mastery
2D Sketch Mastery
Lesson 1 • Sketch Environment Basics
Introduces the sketch plane selection process and the tools used to enter and exit sketch mode. Connects directly to how 3D features are initiated from 2D profiles.
Lesson 2 • Drawing Geometric Entities
Covers lines, arcs, circles, rectangles, splines, and polygons used to build sketch profiles. Accurate geometry here ensures clean 3D features downstream.
Lesson 3 • Geometric and Dimensional Constraints
Teaches how to apply relations such as parallel, tangent, and coincident, plus smart dimensions. Fully constrained sketches are the standard for professional parametric design.
Lesson 4 • Sketch Editing and Repair
Addresses trimming, extending, mirroring, offsetting, and repairing broken sketch geometry. These tools speed up sketch creation and fix common errors before feature creation.
Lesson 5 • Advanced Sketch Techniques
Explores driven dimensions, sketch pictures, and multi-contour sketches for complex profiles. Mastery here enables efficient creation of intricate 3D features.
Chapter 3HideHide detailsSee detailsCore Solid Modeling Features
Core Solid Modeling Features
Lesson 1 • Sweep and Loft Features
Introduces path-driven sweeps and multi-profile lofts for organic and complex geometry. These features handle shapes that extrude and revolve cannot produce.
Lesson 2 • Revolve Features
Teaches revolving a sketch profile around an axis to create cylindrical and rotational geometry. Revolve is essential for shafts, bottles, and any axially symmetric part.
Lesson 3 • Extrude and Extrude Cut
Covers boss-extrude and cut-extrude operations with depth options, draft angles, and end conditions. These are the most frequently used features in any solid modeling workflow.
Lesson 4 • Holes, Patterns, and Mirror
Covers the hole wizard, linear and circular patterns, and mirror features for efficient replication. Patterns dramatically reduce modeling time for repetitive geometry.
Lesson 5 • Fillets, Chamfers, and Shell
Applies edge treatments and wall-thickness operations to refine solid geometry. These finishing features are critical for manufacturability and aesthetic quality.
Chapter 4HideHide detailsSee detailsPart Design and Feature Management
Part Design and Feature Management
Lesson 1 • Design Intent and Parametric Strategy
Teaches how to embed design intent through relations, equations, and strategic constraint placement. Models built with intent update predictably when dimensions change.
Lesson 2 • Multi-Body Part Modeling
Introduces working with multiple solid bodies within a single part file for complex designs. Multi-body techniques enable weldment design and Boolean operations.
Lesson 3 • Feature Tree Organization
Explains the model tree hierarchy, feature renaming, folders, and rollback bar usage. A well-organized tree is essential for collaboration and long-term model maintainability.
Lesson 4 • Editing and Repairing Features
Addresses feature editing, parent-child relationships, and resolving rebuild errors. Efficient repair skills keep projects on schedule when design changes occur.
Lesson 5 • Reference Geometry and Planes
Covers creating reference planes, axes, and points to support complex feature placement. Reference geometry unlocks modeling possibilities beyond the default three planes.
Chapter 5HideHide detailsSee detailsAssembly Modeling and Constraints
Assembly Modeling and Constraints
Lesson 1 • Advanced Mates and Mechanical Relations
Teaches gear, cam, slot, and path mates that simulate real mechanical motion. These mates enable functional validation of mechanisms before physical prototyping.
Lesson 2 • Standard Mates and Constraints
Covers coincident, concentric, parallel, perpendicular, and distance mates to position parts. Correct mating fully defines component position and enables motion simulation.
Lesson 3 • Assembly Performance and Large Assemblies
Addresses lightweight components, SpeedPak, and display states for managing large assemblies. Performance techniques are critical when working with hundreds of components.
Lesson 4 • Assembly-Level Features and Patterns
Covers assembly cuts, holes, and component patterns applied at the assembly level. These features handle geometry that spans multiple parts and cannot exist in a single part.
Lesson 5 • Assembly Environment Overview
Introduces the assembly workspace, component insertion methods, and the assembly feature tree. Understanding this environment is prerequisite to all assembly-level work.
