📘 BCEDK203 – MODULE WISE TOPICS
🔷 MODULE 1: Introduction & Orthographic Projections
- Importance of Engineering Drawing
- BIS conventions
- Freehand sketching & scales
- Introduction to CAD software
- Coordinate system & reference planes (HP, VP, etc.)
-
Basic CAD commands:
- Line, circle, rectangle, polygon
- Move, copy, mirror, rotate
- Trim, extend, fillet, chamfer
-
Orthographic projections of:
- Points
- Lines
- Planes
🔷 MODULE 2: Orthographic Projection of Solids
-
Projection of 3D solids resting on HP:
- Prisms
- Pyramids
- Cylinders
- Cones
- Cube, Tetrahedron
- Practice problems (including frustums)
🔷 MODULE 3: Isometric Projections
(This module is standard though sometimes not fully shown in some sites)
- Isometric projection principles
-
Isometric view of:
- Prisms, pyramids
- Cylinders, cones
-
Conversion:
- 2D → 3D view
- Orthographic → Isometric
👉 Very important for exams
🔷 MODULE 4: Development of Surfaces
-
Development of lateral surfaces:
- Prisms
- Pyramids
- Cylinders
- Cones
-
Development of:
- Frustums
- Truncated solids
-
Applications:
- Funnels
- Trays
- Transition pieces (ducts)
🔷 MODULE 5: Multidisciplinary Applications
-
Freehand sketching:
- Buildings, tools, furniture
-
Drawing simple mechanisms:
- Bicycle, gear systems, carts
-
Electrical drawings:
- Wiring diagrams (bell, alarm, UPS)
-
Building drawings:
- Floor plans, foundation
- Trusses, bridges
-
Electronics drawings:
- Basic circuits
-
Graphs & charts:
- Pie chart, line graph, Gantt chart
