Draughting and Design Course

Lesson 1 • Line Types and Standards

Introduces standardised line weights, types, and their functional meanings in technical drawings. Connects line conventions to professional readability requirements.

Lesson 2 • Drawing Sheet Layout and Title Blocks

Covers standard sheet sizes, border setup, and title block content requirements. Ensures every drawing produced meets professional presentation standards.

Lesson 3 • Basic Geometric Construction

Teaches construction of fundamental geometric shapes using compass, straightedge, and CAD tools. Provides the geometric vocabulary needed for all drafting work.

Lesson 4 • Drawing Tools and Equipment

Covers manual and digital drafting instruments, their correct use, and maintenance. Establishes the physical foundation for all subsequent drawing tasks.

Lesson 1 • Selecting and Arranging Views

Teaches criteria for choosing the minimum necessary views to fully describe an object. Proper view selection reduces drawing complexity and reading errors.

Lesson 2 • Auxiliary Views

Teaches construction of primary and secondary auxiliary views for inclined surfaces. Auxiliary views complete the description of features not parallel to principal planes.

Lesson 3 • Hidden Lines and Centre lines

Covers rules for showing internal features and axes of symmetry across all views. Accurate hidden-line and centreline use prevents misinterpretation of geometry.

Lesson 4 • Principles of Orthographic Projection

Explains first-angle and third-angle projection theory and their global usage contexts. Establishes the conceptual framework for all multiview drawing work.

Lesson 1 • Size and Location Dimensions

Distinguishes size dimensions from location dimensions and applies each correctly. Proper classification ensures parts are manufactured and assembled as intended.

Lesson 2 • Tolerancing Concepts

Introduces limit, bilateral, and unilateral tolerances and their effect on fit and function. Tolerance selection directly impacts manufacturing cost and part interchangeability.

Lesson 3 • Dimensioning Fundamentals

Covers dimension line placement, arrowhead styles, and basic dimensioning rules. Correct fundamentals prevent ambiguity in manufacturing and inspection.

Lesson 4 • Surface Finish and Weld Symbols

Teaches surface texture notation and standard weld symbols used on production drawings. These symbols complete the manufacturing specification on a finished drawing.

Lesson 1 • Oblique Drawing Methods

Teaches cavalier and cabinet oblique projection and their appropriate applications. Oblique drawing simplifies representation of objects with complex front faces.

Lesson 2 • Shading and Rendering Basics

Introduces light source conventions, line shading, and basic rendering for pictorial clarity. Rendering enhances visual communication in client presentations and catalogues.

Lesson 3 • Isometric Drawing Principles

Covers isometric axes, scale, and construction methods for rectilinear and curved objects. Isometric drawing is the most widely used pictorial format in technical documentation.

Lesson 4 • One- and Two-Point Perspective

Introduces vanishing point theory and construction of one- and two-point perspective views. Perspective drawing communicates spatial relationships in architectural and product contexts.

Lesson 1 • Layers, Blocks, and Templates

Covers layer management, reusable block creation, and drawing template setup. These tools enforce standards and dramatically increase drafting efficiency.

Lesson 2 • CAD Interface and Navigation

Covers workspace layout, command entry methods, and display controls in a CAD environment. Efficient navigation is the prerequisite for all productive CAD drafting work.

Lesson 3 • Drawing Output and File Management

Covers plot settings, paper space layouts, and file format export for professional delivery. Correct output procedures ensure drawings are usable by all downstream stakeholders.

Lesson 4 • 2D Drawing and Editing Commands

Teaches core draw and modify commands for creating precise 2D geometry. Mastery of these commands forms the backbone of all 2D CAD production work.

Lesson 1 • Structural Details and Connections

Covers detailing of foundations, beams, columns, and connection nodes at large scale. Structural details communicate critical load-path information to contractors and engineers.

Lesson 2 • Architectural Symbols and Conventions

Covers standard symbols for walls, doors, windows, stairs, and material hatching. Consistent symbol use ensures drawings are readable by all project team members.

Lesson 3 • Dimensioning Architectural Drawings

Teaches architectural dimensioning conventions including string dimensions and grid lines. Architectural dimensioning differs from mechanical practice and must be applied correctly.

Lesson 4 • Architectural Drawing Types

Introduces floor plans, elevations, sections, and site plans as components of a drawing set. Understanding each type's purpose enables correct content and presentation decisions.

Lesson 1 • Fastener and Hardware Representation

Covers simplified and detailed representation of threaded fasteners, keys, and pins. Correct fastener representation prevents assembly errors and procurement mistakes.

Lesson 2 • Detail Drawing Requirements

Covers the content requirements of a fully defined detail drawing for a single manufactured part. Every element must be present for the drawing to serve as a manufacturing contract.

Lesson 3 • Assembly Drawing Practices

Teaches assembly drawing layout, part balloon placement, and view selection for assemblies. Assembly drawings communicate how individual parts combine into a functional product.

Lesson 4 • Castings, Forgings, and Sheet Metal

Introduces drawing conventions specific to cast, forged, and sheet metal parts. Each manufacturing process requires unique drawing notes and geometric conventions.

Lesson 1 • Complex Geometry and Transitions

Covers development of complex surfaces, transitions, and intersections for fabrication drawings. These techniques are required for ductwork, vessels, and complex structural forms.

Lesson 2 • Design Intent and Drawing Strategy

Teaches how to translate design intent into a drawing strategy that minimises ambiguity. Strategic planning before drafting reduces rework and improves downstream usability.

Lesson 3 • Drawing Review and Quality Control

Covers systematic drawing review checklists, peer review processes, and error classification. Quality control at the drawing stage prevents costly downstream manufacturing errors.

Lesson 4 • Parametric and Associative Drawing

Introduces parametric constraints and model-based drawing generation in CAD. Associative drawings update automatically when the 3D model changes, reducing manual rework.
