Free CAD Drafting Course
CAD Drafting and 3D Modeling
Get familiar with CAD drafting, drawing views, dimensions, layers, layouts, and simple 3D model setup. Join this free CAD drafting course to understand how design drawings are prepared.
About this course
This free CAD drafting course introduces the drawing logic used to turn design ideas into clear digital documents. You will learn how CAD drafting and 3D modeling connect through lines, shapes, layers, dimensions, views, layout planning, annotations, and basic model setup. The course is meant for beginners who want to understand how technical drawings are organized before using advanced design software or working with detailed project files.
The lessons help you see why drafting accuracy, scale, symbols, and clean layouts matter in design, engineering, construction, manufacturing, and product planning. You can use this foundation to read CAD drawings, discuss design changes, prepare simple layouts, and decide whether to continue into AutoCAD, mechanical drafting, architectural drafting, or 3D design training. The course focuses on core concepts and practical drawing awareness without claiming professional software mastery.
Course outline
Understanding Technical Drawing Fundamentals
In this module, you'll learn why technical drawings matter, the main drawing types and standards, line types, first-angle and third-angle projection, scale, and title blocks.
Navigating CAD Software Environments
In this module, you'll learn your way around the CAD workspace, coordinate systems, units and templates, layers, snaps for precision, reusable blocks, and file formats like DWG and STEP.
Mastering 2D Drafting and Geometric Construction
In this module, you'll learn to draw lines, arcs and polygons, edit with trim, offset, fillet and mirror, create section, auxiliary and detail views, and catch common errors.
Dimensioning and Tolerancing Best Practices
In this module, you'll learn to dimension drawings clearly, choose baseline or chain dimensioning, apply tolerances and basic GD&T, add notes and a bill of materials, and track revisions.
Building 3D Models: Solid and Surface Modeling
In this module, you'll learn to turn 2D sketches into 3D parts using extrude, revolve, sweep and loft, add holes and fillets, edit the feature tree, and export models.
Creating Assemblies and Parametric Models
In this module, you'll learn parametric design, how to join parts with mates and constraints, check for interference, make exploded views, and manage design variants with configurations.
Finalizing Drawings for Production and Collaboration
In this module, you'll learn to lay out and plot sheets, follow templates and naming rules, control versions, share PDFs for markup, and run a quality check before release.
Advanced CAD Workflows and Emerging Industry Practices
In this module, you'll learn how CAD connects to CAM, BIM and simulation, sheet metal and design for manufacturing basics, AI-assisted drafting, and how to build a portfolio.
