Engineering Graphics & Design Syllabus (BTME101-21)

Course Objectives

The objective of this course is to introduce the students to the basics of engineering drawing and provide them with the fundamental skills and knowledge required to visualize, communicate, and document engineering designs effectively.

Course Outcomes

On completion of this course students will be able to:

• Prepare and understand drawings.
• Use the principles of orthographic projections.
• Visualize three dimensional objects and that will enable them to design new products.
• Design and fabricate surfaces of different shapes.
• Represent the objects in three dimensional appearances.

Detailed Syllabus

UNIT-I (18 Hrs.)

• INTRODUCTION TO ENGINEERING DRAWING: Principles of engineering drawing / engineering graphics / technical drawing and their significance - Drawing Instruments: their Standard and uses symbols and conventions in drawing practice - lettering & numbering - BIS conventions.
• Types of lines and their uses, Drawing Sheets: sizes and layout, methods of folding drawing sheet, Grades of pencils used, Dimensioning: definition, types and methods of dimensioning, geometrical construction, concept of scales in drawing, types of scales, construction of plane and diagonal scales.

UNIT-II (12 Hrs.)

• ORTHOGRAPHIC PROJECTIONS: Relevance of projection, Types of projections, Principles of orthographic projections in reference to quadrants conventions first and third angle projections, illustration through simple problems of projection.
• Projections of points in quadrants.
• Projections and trace of a line with different possible orientations in a quadrant.
• Methods to find true length and inclination of a line with principal planes.

UNIT-III (18 Hrs.)

• PROJECTIONS OF PLANES AND SOLIDS: Concept of plane and lamina, Projections of a lamina when; parallel to any reference plane, perpendicular to any reference plane, inclined to reference plane.
• Traces of planes.
• Definition of solid, types of solids - conventions-different possible orientations of solid in a quadrant.
• Projections of solid when; axis parallel to reference plane, perpendicular to reference plane, inclined to one and parallel to other reference plane, parallel to both horizontal and vertical planes.

UNIT-IV (12 Hrs.)

• ISOMETRIC PROJECTIONS: Principles of Isometric Projections-Isometric Scale- Isometric Views or drawing- Conventions.
• Isometric drawing / projections of solids such as cube, prisms, pyramids, cylinder, and cone.

UNIT-V (12 Hrs.)

• Practice using Computer Aided Drafting (CAD) tools: Hands on training on any CAD software to strengthen the understanding of the engineering drawing wherein the students will be introduced to a number of assignments as mentioned in the syllabus.
