About Course

Engineering drawing is the standardized graphical language used by engineers, architects, and designers to communicate the shape, size, dimensions, and specifications of objects or structures. It uses precise lines, symbols, scales, and projections to represent components accurately for manufacturing, construction, and assembly. Common types include orthographic projections, isometric views, sectional views, and dimensioned drawings. Engineering drawing is essential in fields such as mechanical, civil, electrical, and aerospace engineering because it ensures clear communication and reduces errors during production.

23MET102 ENGINEERING DRAWING L T P C [Common to all Non Circuit Branches] 1 0 4 3 COURSE OBJECTIVES: ᧢ To provide a common language for engineers and manufacturers to communicate design ideas, specifications, and requirements. ᧢ To acquire skills in creating and interpreting 2D and 3D representations of components, assemblies and systems. UNIT I PROJECTION OF POINTS, LINES AND PLANE SURFACES 3+12 Projection of points - Projection of straight lines located in the first quadrant -Determination of true Lengths and true inclinations - Projection of polygonal surface and circular lamina inclined to both reference planes. UNIT II PROJECTION OF SOLIDS 3+12 Projection of simple solids like prisms, pyramids, cylinder and cone when the axis is inclined to one reference plane by change of position method. UNIT III SECTION OF SOLIDS AND DEVELOPMENT OF SURFACES 3+12 Sectioning of above solids in simple vertical position by cutting planes inclined to one reference plane and perpendicular to the other -Obtaining true shape of section. Development of lateral surfaces of Simple and truncated solids -Prisms, pyramids, cylinders and cones. UNIT IV PICTORIAL PROJECTIONS AND FREE HAND SKETCHING 3+12 Principles of isometric projection -isometric scale -isometric projections of simple solids, truncated prisms, pyramids, cylinders and cones. Free hand sketching: Representation of Three Dimensional objects -Need for importance of multiple views and their placement -First angle projection -layout views -Developing visualization skills through free hand sketching of multiple views from pictorial drawing. Perspective projection of prisms, pyramids and cylinders by visual ray method (Not for Examination). UNIT V BUILDING DRAWING 3+12 Drawing of a plan, Elevation and sectioning of security room and residential building (Two bed rooms, kitchen, hall, etc.) Practicing design in the CAD Software (Not for Examination).
