(15A03101) ENGINEERING DRAWING

Objectives:

• To gain and understanding of the basics of geometrical constructions of various planes and solids, understanding system of graphical representation of various objects and various views to draft and read the products to be designed and eventually for manufacturing applications.
• To learn about various projections, to understand complete dimensions and details of object.
• Ultimately student must get imaginary skill to put an idea of object, circuit, assembly of parts in black & white, to design a product and to understand the composition, which can be understood universally.

Syllabus:

UNIT I

Introduction to Engineering Drawing: Principles of Engineering Graphics and their Significance-Conventions in Drawing-Lettering – BIS Conventions. Curves used in Engineering Practice. a) Conic Sections including the Rectangular Hyperbola- General method only, b) Cycloid, Epicycloid and hypocycloid 

UNIT II

Scales: Plain, Diagonal and Vernier;Projection of Points: Principles of orthographic projection – Convention – First angle projections,projections of points.

UNIT III

Projections of Lines: lines inclined to one or both planes, Problems on projections, Finding True lengths.

Projections of Planes: Projections of regular plane surfaces- plane surfaces inclined to both planes.

UNIT IV

Projections of Solids: Projections of Regular Solids with axis inclined to both planes.

Developments of Solids: Development of Surfaces of Right Regular Solids-Prism, Cylinder,

Pyramid, Cone.

UNIT V

Isometric and Orthographic Projections: Principles of isometric projection- Isometric Scale-

Isometric Views- Conventions- Isometric Views of lines, Planes, Simple solids (cube,cylinder and cone). Isometric projections of spherical parts. Conversion of isometric Views to Orthographic Views.
