3D CAD Applications Course

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 modeling tasks.

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 modeling 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 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 moldability, 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 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 Modeling

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 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 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 organizational 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 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 Modeling

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 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 Modeling

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 Optimization

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