Rationale:

Engineering graphics is a basic subject for all branches of Diploma Engineering and Technology. Since engineering drawing is considered as the language of engineers, the proper understanding and practice is required with proper instruments.

This subject is aimed at providing basic understanding of the fundamentals of Engineering Drawing; mainly visualization, graphics theory, standards & conventions of drawing, the tools of drawing and the use of Drawings in engineering applications.

The topics covered are based on the syllabus for Diploma studies in engineering. The subject is planned to include sufficient practices which would help the student in visualization of three dimensional objects and developing the drawing.

The chapters are arranged in sequence and starts from the basic concepts of geometrical constructions & engineering curves, proceeds to the principles of projection techniques. By the end of the subject it is expected that the students would be matured to visualize any engineering component by reading an engineering drawing.

Objectives:

At the end of the practice, the students will be able to,

• Understand the importance of drawing.
• Identify and use the drawing instruments.
• Practice the rules and methods of dimensioning.
• Acquire knowledge about geometric construction.
• Construct conics curves.
• Draw the projection ofpoints and straight lines.
• Draw orthographic views from isometric drawings.

Unit 2

Geometric Constructions

Geometric constructions: Bisect a line – bisect an arc – bisect given angle – divide straight line into number of equal parts – divide the circle into number of equal divisions – draw an arc touching two lines at any angle -draw an arc touching two arcs. 20

Constructions of conics

Conics: Cone – conic sections – Definition of locus, focus, directrix, axis, vertex and eccentricity. Definition: ellipse, parabola and hyperbola. Ellipse: Construction of ellipse by concentric circle method, rectangular method and Eccentricity method when focus and directrix are given -Exercises. Parabola: Construction of parabola by rectangular method, parallelogram method and eccentricity method when focus and directrix are givenexercises. Hyperbola: Construction of hyperbola by rectangular method and eccentricity method when focus and directrix are given – exercises.

Unit 3

Projection of points:

Projection of points – points on the different quadrants and on the reference planes.

Projection of straight lines:

Projection of straight lines – Line in the first quadrant and on the reference planes – perpendicular to one plane and parallel to other plane – inclined to one plane and parallel to the other plane – parallel to both the planes -inclined to both the planes – Exercises. 17
