Course content

8 Chapters • 40 LessonsDuration between 4 and 360 hours (you decide)

Chapter 1See details

Introduction to 3D CAD Fundamentals

  • Lesson 1 • Coordinate Systems and 3D Space

    Explains Cartesian coordinates, axes orientation, and planes in 3D space. Students gain spatial reasoning needed for accurate model placement.

  • Lesson 2 • File Management and Project Setup

    Covers file formats, templates, units, and project folder structures. Proper setup prevents errors and ensures compatibility across workflows.

  • Lesson 3 • CAD Industry Overview and Applications

    Covers the role of 3D CAD across engineering, architecture, and manufacturing. Establishes context for why CAD skills are professionally essential.

  • Lesson 4 • Basic Geometry Creation

    Introduces primitive shapes, lines, and basic drawing tools in 3D space. These building blocks underpin all subsequent modelling tasks.

  • Lesson 5 • Navigating the CAD Interface

    Introduces the workspace layout, toolbars, menus, and viewport controls. Proficiency here enables efficient workflow throughout the course.

Chapter 2See details

2D Sketching and Constraint-Based Design

  • Lesson 1 • Advanced Sketch Techniques

    Explores construction geometry, sketch patterns, and mirroring for complex profiles. These techniques reduce redundant work and improve sketch accuracy.

  • Lesson 2 • Dimensional Constraints and Parameters

    Covers driven and driving dimensions that control sketch size and position. Parametric dimensions enable rapid design iteration later in the workflow.

  • Lesson 3 • Sketch Best Practices and Troubleshooting

    Addresses over-defined sketches, dangling references, and design intent strategies. Clean sketches prevent downstream modelling failures.

  • Lesson 4 • Geometric Constraints

    Teaches relationships such as parallel, perpendicular, tangent, and coincident. Constraints lock sketch geometry to design intent without numeric input.

  • Lesson 5 • Sketching Tools and Environments

    Introduces the dedicated sketch environment and its core drawing tools. Mastery of these tools is the prerequisite for parametric 3D modelling.

Chapter 3See details

Solid Modelling Core Techniques

  • Lesson 1 • Pattern and Mirror Features

    Automates repetitive geometry using linear, circular, and mirror operations. Patterns maintain design intent and reduce manual feature duplication.

  • Lesson 2 • Shell, Draft, and Rib Features

    Covers hollowing solids, adding taper for mouldability, and creating structural ribs. These features are essential for plastic and cast-part design.

  • Lesson 3 • Sweep and Loft Features

    Introduces path-driven sweeps and multi-profile lofts for complex shapes. Students model organic and transitional geometries beyond simple extrusions.

  • Lesson 4 • Extrude and Revolve Features

    Covers the two most fundamental sketch-to-solid operations: extrusion and revolution. These features form the basis of most mechanical part geometries.

  • Lesson 5 • Fillet, Chamfer, and Edge Treatments

    Teaches edge-rounding and chamfering operations critical for manufacturability and aesthetics. Proper edge treatment reduces stress concentrations in real parts.

Chapter 4See details

Part Design and Feature Management

  • Lesson 1 • Equations and Design Tables

    Introduces formula-driven dimensions and spreadsheet-based configuration control. These tools enable families of parts from a single model file.

  • Lesson 2 • Multi-Body Part Modelling

    Teaches creating and managing multiple solid bodies within one part file. Multi-body techniques support complex machined and weldment designs.

  • Lesson 3 • Reference Geometry Creation

    Covers planes, axes, and points used to anchor features to design intent. Reference geometry enables complex feature placement beyond default planes.

  • Lesson 4 • Model Editing and Repair Strategies

    Addresses editing absorbed features, resolving rebuild errors, and repairing broken references. These skills keep models functional after design changes.

  • Lesson 5 • Feature Tree Organisation

    Explains the feature history tree, feature order, and rollback capabilities. A well-organised tree makes models easier to edit and share with colleagues.

Chapter 5See details

Assembly Modelling and Constraints

  • Lesson 1 • Advanced Mates and Mechanical Relations

    Introduces gear, cam, slot, and path mates for kinematic assemblies. These mates simulate real mechanical motion between components.

  • Lesson 2 • Interference Detection and Motion Study

    Teaches collision checking and basic kinematic motion simulation. These analyses validate assembly function before physical prototyping.

  • Lesson 3 • Assembly Environment Fundamentals

    Introduces the assembly workspace, component insertion, and the assembly tree. Understanding this environment is required before applying any constraints.

  • Lesson 4 • Assembly Patterns and Configurations

    Covers component patterns, mirroring, and configuration-based assembly variants. These tools manage repetitive components and multiple assembly states.

  • Lesson 5 • Standard Mates and Constraints

    Covers coincident, concentric, parallel, and distance mates for component alignment. Correct mating replicates physical assembly relationships in the model.

Chapter 6See details

Engineering Drawings and Annotations

  • Lesson 1 • View Creation and Projection

    Teaches standard orthographic, auxiliary, section, and detail views. Correct view selection communicates part geometry unambiguously to manufacturers.

  • Lesson 2 • Bill of Materials and Drawing Notes

    Covers BOM tables, balloon callouts, surface finish symbols, and general notes. Complete documentation reduces manufacturing ambiguity and procurement errors.

  • Lesson 3 • Drawing Environment and Sheet Setup

    Covers drawing templates, title blocks, sheet scales, and paper sizes. Proper setup ensures drawings conform to organisational and industry standards.

  • Lesson 4 • Geometric Dimensioning and Tolerancing

    Introduces GD&T symbols, datum references, and feature control frames. GD&T communicates functional tolerances more precisely than coordinate tolerancing.

  • Lesson 5 • Dimensions and Tolerances

    Covers smart dimensioning, tolerance types, and fit specifications on drawings. Accurate tolerancing ensures parts assemble and function as designed.

Chapter 7See details

Surface Modelling Techniques

  • Lesson 1 • Surface Editing and Trimming

    Teaches trimming, extending, knitting, and filling surface gaps. Editing tools refine raw surfaces into clean, manufacturable geometry.

  • Lesson 2 • Hybrid Solid-Surface Modelling

    Combines surface and solid bodies to achieve shapes impossible with solids alone. Hybrid workflows are standard in industrial and product design.

  • Lesson 3 • Core Surface Creation Tools

    Covers extruded, revolved, swept, and lofted surfaces as the primary creation methods. These mirror solid features but produce zero-thickness surface bodies.

  • Lesson 4 • Surface Quality Analysis

    Introduces curvature combs, zebra stripes, and draft analysis for surface evaluation. Quality checks ensure surfaces meet aesthetic and manufacturing requirements.

  • Lesson 5 • Surface Modelling Concepts

    Distinguishes surface bodies from solid bodies and explains when surfaces are preferred. This conceptual foundation prevents misuse of surface tools.

Chapter 8See details

Advanced CAD Workflows and Optimisation

  • Lesson 1 • Design Automation with Macros

    Introduces recording and editing macros to automate repetitive CAD tasks. Automation reduces errors and accelerates production of standard deliverables.

  • Lesson 2 • Top-Down Design and In-Context Modelling

    Teaches creating parts within the assembly context using external references. Top-down design ensures components fit together by definition.

  • Lesson 3 • Data Exchange and Interoperability

    Covers neutral file formats, translation settings, and import repair workflows. Reliable data exchange is critical for multi-software and multi-vendor projects.

  • Lesson 4 • Model Performance and Rebuild Optimisation

    Addresses feature order, sketch complexity, and geometry simplification for faster rebuilds. Optimised models reduce iteration time on large projects.

  • Lesson 5 • Large Assembly Management

    Covers lightweight components, SpeedPak, and display states for performance in large assemblies. These techniques prevent system slowdowns on complex projects.
