9 notes for Engineering Graphics, unit by unit.

Unit 1 · Short notes Module 1: Introduction to Engineering Drawing Principles of Engineering Graphics and their significance · Usage of drawing instruments · Lettering · Conic sections including rectangular hyperbola · Cycloid, epicycloid, hypocycloid and involute · Scales – plain, diagonal and vernier scales
Unit 2 · Short notes Module 2: Orthographic Projections Principles of orthographic projections and conventions · Projection of points and lines inclined to both planes · Projection of inclined planes and auxiliary planes
Unit 3 · Short notes Module 3: Projections of Regular Solids and Floor Plans Projections of regular solids and inclined solids with auxiliary views · Simple annotation, dimensioning and scale · Floor plan drawing including windows, doors, and fixtures (WC, bath, sink, shower, etc.)
Unit 4 · Short notes Module 4: Sections and Sectional Views of Right Angular Solids Sections and sectional views of right angular solids (prism, cylinder, pyramid, cone) with auxiliary views · Development of surfaces of right regular solids · Drawing sectional orthographic views of geometric solids and industry/dwelling objects (foundation to slab only)
Unit 5 · Short notes Module 5: Isometric Projections Principles of isometric projection and isometric scale · Isometric views and conventions · Isometric views of lines, planes, simple and compound solids · Conversion of isometric views to orthographic views and vice‑versa
Unit 6 · Short notes Module 6: Overview of Computer Graphics and CAD Theory Computer graphics technologies impacting graphical communication · Theory of CAD software – menu system, toolbars, drawing area, dialogs, shortcut menus, command line, status bar, zoom methods, select/erase objects · Isometric views of lines, planes, simple and compound solids (CAD implementation)
Unit 7 · Short notes Module 7: Customisation & CAD Drawing Setup of drawing page and printer including scale settings · Setting up units and drawing limits · ISO and ANSI standards for coordinate dimensioning and tolerancing · Orthographic constraints and snapping to objects (manual and automatic) · Producing drawings using coordinate input methods for straight lines and circles
Unit 8 · Short notes Module 8: Annotations, Layering & Other Functions Applying dimensions and annotations to objects · Layer setup and usage – creating, editing and customizing layers · Modifying line lengths (extend/lengthen) · Printing drawings to paper · Orthographic projection techniques · Drawing sectional views of composite right regular geometric solids and projecting true shapes
Unit 9 · Short notes Module 9: Design Project and BIM Introduction Team design project illustrating geometry and topology of engineered components · Creation of engineering models and presentation in standard 2D blueprint form and as 3D wire‑frame and shaded solids · Meshed topologies for engineering analysis and tool‑path generation for component manufacture · Geometric dimensioning and tolerancing (GD&T) · Use of solid‑modeling software for creating associative models at component and assembly levels · Floor plans including windows, doors and fixtures (WC, bath, sink, shower, etc.)
