Technical Drawing Course

Lesson 1 • Industry Standards and Drawing Sheets

Introduces international and national drawing standards, sheet sizes, and title block requirements. Ensures all student output conforms to professional documentation norms.

Lesson 2 • Line Types and Their Meanings

Defines the full vocabulary of line types used in technical drawing and their specific communicative functions. Connects line selection to accurate drawing interpretation.

Lesson 3 • Basic Geometric Construction

Teaches manual construction of fundamental geometric shapes using compass and straightedge. Provides the spatial reasoning skills needed for accurate technical sketching.

Lesson 1 • Front, Top, and Side Views

Guides students through selecting and drawing the three principal views of an object. Reinforces alignment rules and view correspondence across projections.

Lesson 2 • Auxiliary and Section Views

Extends orthographic projection to inclined surfaces and internal features. Students learn when and how to apply auxiliary and section views for complete part description.

Lesson 3 • Projection Theory and Planes

Explains the conceptual basis of projection planes and how 3D objects map onto 2D surfaces. Anchors all multi-view drawing in a rigorous spatial model.

Lesson 1 • Dimensioning Specific Features

Applies dimensioning rules to holes, arcs, angles, chamfers, and threads. Ensures students can annotate every common industrial feature correctly.

Lesson 2 • Limits, Fits, and Tolerances

Introduces the concept of interchangeable manufacture through limits, fits, and tolerance systems. Students apply tolerance notation to ensure parts assemble correctly.

Lesson 3 • Geometric Dimensioning and Tolerancing

Introduces GD&T symbols, datums, and feature control frames for precise form and position control. Connects GD&T to functional part requirements and inspection.

Lesson 1 • Drawing Completeness and Review

Establishes a systematic checklist approach to verifying that a drawing fully defines a part. Students practise self-review and peer-review techniques used in industry.

Lesson 2 • Advanced Section View Techniques

Extends basic sectioning to complex parts with multiple features and non-standard cutting planes. Reinforces correct hatching, labelling, and view placement.

Lesson 3 • Detail and Enlarged Views

Teaches creation of enlarged detail views to clarify small or complex features. Students learn scaling, labelling, and referencing conventions for detail callouts.

Lesson 1 • Isometric Drawing Fundamentals

Introduces the isometric grid, axis orientation, and the rules for transferring orthographic dimensions. Students draw simple prismatic objects in correct isometric form.

Lesson 2 • Oblique and Cabinet Projection

Covers cavalier and cabinet oblique projection as alternatives to isometric for face-dominant objects. Students select the most appropriate pictorial method for a given part.

Lesson 3 • Isometric Drawing of Complex Parts

Applies isometric techniques to parts with holes, slots, inclined surfaces, and curved features. Builds confidence in representing real industrial components pictorially.

Lesson 1 • Threaded Fastener Representation

Covers simplified, schematic, and detailed thread representations for bolts, screws, and nuts. Students apply correct callout formats for metric and unified thread systems.

Lesson 2 • Weld Symbols and Joints

Teaches the full weld symbol system including reference line, arrow, tail, and supplementary symbols. Students specify weld type, size, and location for common joint configurations.

Lesson 3 • Keys, Pins, and Retaining Rings

Covers the drawing and specification of shaft keys, dowel pins, cotter pins, and retaining rings. Ensures students can fully document shaft-hub connections and retention features.

Lesson 1 • Working Drawing Set Organisation

Teaches how to organise a complete drawing package including assembly, subassembly, and detail sheets. Students structure a drawing set that supports manufacturing and inspection workflows.

Lesson 2 • Assembly Drawing Types and Purpose

Distinguishes design, general, and installation assembly drawings and their specific industrial uses. Students select the correct assembly drawing type for a given communication need.

Lesson 3 • Interpreting and Redlining Drawings

Develops skills for reading, interpreting, and marking up existing working drawings for revision. Students practise industry-standard redline markup and change-order documentation.

Lesson 1 • Layouts, Viewports, and Plotting

Teaches paper-space layouts, viewport scaling, and plot configuration for professional drawing output. Students produce correctly scaled, fully titled plotted drawings ready for release.

Lesson 2 • CAD Drawing Management

Covers file naming, external references, and drawing audit tools for maintaining a clean CAD environment. Students apply file management practices that support team-based drafting workflows.

Lesson 3 • 2D Drawing and Editing Commands

Covers the core draw and modify commands needed to construct any 2D technical geometry. Students build speed and accuracy through structured command practice.

Lesson 4 • CAD Dimensioning and Annotation

Applies CAD dimension styles, text styles, and annotation tools to produce standards-compliant drawing annotations. Students configure dimension styles to match industry requirements.
