Draughtsman Course

Lesson 1 • Drafting Tools and Their Uses

Covers manual and digital drafting instruments, their selection, and proper handling. Builds the tool literacy required for all subsequent drawing tasks.

Lesson 2 • Drawing Sheet Layout and Title Blocks

Explains standard sheet sizes, borders, and title block content. Proper layout ensures drawings meet professional submission requirements.

Lesson 3 • Line Types and Standards

Introduces standardized line conventions used in technical drawings. Correct line usage ensures drawings are universally readable across industries.

Lesson 4 • Freehand Sketching Techniques

Develops hand-eye coordination for rapid idea capture through freehand sketching. Sketching skills support design communication before formal drawings are produced.

Lesson 1 • Scales and Proportional Drawing

Introduces representative scales and the use of scale rules for enlargement and reduction. Correct scaling ensures drawings accurately represent real-world dimensions.

Lesson 2 • Basic Geometric Constructions

Covers bisection, perpendiculars, and parallel lines using compass and straightedge. These operations underpin every subsequent geometric drawing task.

Lesson 3 • Conic Sections and Special Curves

Covers ellipse, parabola, hyperbola, and involute construction methods. These curves appear in engineering profiles, cams, and architectural forms.

Lesson 4 • Circles, Arcs, and Tangents

Explains construction of circles, arcs, and tangent relationships between curves and lines. Tangency is fundamental to smooth profile and cam design.

Lesson 1 • Dimensioning Principles and Practice

Establishes rules for placing dimensions, tolerances, and notes on orthographic drawings. Correct dimensioning enables manufacture without ambiguity.

Lesson 2 • Principles of Orthographic Projection

Explains the theory of projection planes and the relationship between views. Understanding projection theory is the conceptual core of all technical drawing.

Lesson 3 • Drawing the Three Principal Views

Guides students through constructing front, top, and side views from a 3D object. Accurate multi-view drawing is the primary deliverable of a draughtsman.

Lesson 4 • Sectional Views and Conventions

Covers full, half, offset, and revolved sections with correct hatching conventions. Sections expose internal features that cannot be shown with hidden lines alone.

Lesson 1 • One-Point Perspective Drawing

Introduces vanishing-point perspective for interior and exterior architectural views. One-point perspective conveys spatial depth for client presentations.

Lesson 2 • Two-Point Perspective Drawing

Extends perspective to two vanishing points for exterior building and product views. Two-point perspective produces more realistic representations than one-point.

Lesson 3 • Oblique Drawing Methods

Covers cavalier and cabinet oblique drawing with correct axis angles and foreshortening. Oblique drawing is suited to objects with complex front faces.

Lesson 4 • Isometric Drawing and Projection

Teaches construction of isometric drawings using the 30-degree axis system. Isometric views are the most common pictorial format in engineering documentation.

Lesson 1 • Tolerancing for Assemblies

Applies tolerance analysis to multi-part assemblies to ensure interchangeability. Students learn worst-case and statistical tolerance methods for real design scenarios.

Lesson 2 • Geometric Dimensioning and Tolerancing

Introduces GD&T symbols for form, orientation, location, and runout tolerances. GD&T communicates functional requirements that size tolerances alone cannot express.

Lesson 3 • Surface Texture Notation

Covers roughness parameters, surface texture symbols, and machining allowance callouts. Surface specification ensures parts meet functional and aesthetic requirements.

Lesson 4 • Limits, Fits, and Tolerances

Explains tolerance grades, fundamental deviations, and the hole-basis and shaft-basis systems. Correct fit specification prevents assembly failures in production.

Lesson 1 • CAD Interface and Setup

Covers workspace configuration, units, grid, and snap settings in a CAD environment. Correct setup prevents errors and establishes efficient drafting workflows.

Lesson 2 • 2D Drawing and Editing Commands

Teaches line, arc, circle, polyline, and editing commands for 2D geometry creation. Mastery of these commands enables rapid and accurate CAD drawing production.

Lesson 3 • Layers, Blocks, and Attributes

Explains layer management, block creation, and attribute-driven title blocks. Blocks and layers are the organizational backbone of professional CAD drawings.

Lesson 4 • Plotting, Layouts, and Drawing Output

Teaches paper space layouts, viewport configuration, and plot style management. Correct output settings ensure drawings print to standard sheet sizes and scales.

Lesson 1 • Floor Plans and Site Plans

Teaches layout and dimensioning of floor plans and their relationship to site plans. Floor plans are the primary reference document in any building project.

Lesson 2 • Elevations and Building Sections

Guides construction of exterior elevations and vertical building sections. Elevations and sections communicate height, material, and structural relationships.

Lesson 3 • Architectural Drawing Conventions

Covers symbols, line weights, and notation specific to architectural drawings. Architectural conventions differ from mechanical drafting and must be mastered separately.

Lesson 4 • Services and Utility Layouts

Introduces schematic layouts for plumbing, drainage, and electrical distribution. Services drawings coordinate trades and prevent clashes during construction.

Lesson 1 • Pipe and Fluid System Drawings

Introduces piping and instrumentation diagrams and isometric pipe drawings. Pipe drawings are essential in process, HVAC, and hydraulic system documentation.

Lesson 2 • Fasteners and Standard Components

Explains simplified and detailed representation of bolts, nuts, keys, and bearings. Standard component representation speeds drawing production and reduces errors.

Lesson 3 • Assembly and Sub-Assembly Drawings

Covers general arrangement and sub-assembly drawings with parts lists. Assembly drawings communicate how components fit together and in what sequence.

Lesson 4 • Detail Drawing Production

Teaches complete detail drawing creation for individual machined parts. Detail drawings are the primary documents used by machinists and fabricators.
