    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 2See details

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 3See details

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 4See details

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 5See details

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.

Chapter 6See details

Engineering Drawings and Annotation

  • Lesson 2 • Design Tables for Automation

    Teaches building spreadsheet-driven design tables to auto-generate multiple configurations. Design tables eliminate manual repetition when managing large product families.

  • Lesson 3 • Assembly Configurations

    Covers component suppression, mate suppression, and display states within assembly configurations. Assembly configurations enable showing different product states in a single file.

  • Lesson 4 • Custom Properties and Metadata

    Covers flex, wrap, dome, and deform features for shaping geometry beyond standard extrudes. These tools address industrial design and ergonomic shaping requirements.

  • Lesson 4 • Curvature Analysis and Quality Control

    Uses zebra stripes, curvature combs, and draft analysis to evaluate surface quality. Analysis tools ensure surfaces meet aesthetic and manufacturing requirements.

  • Lesson 5 • Hybrid Solid-Surface Modeling

    Combines surface and solid tools to achieve shapes impossible with solids alone. Hybrid workflows are standard practice in consumer product and automotive design.
