# GE3251: Engineering Graphics syllabus for TT 2021 regulation

Engineering Graphics detailed syllabus for Textile Technology (TT) for 2021 regulation curriculum has been taken from the Anna University official website and presented for the TT students. For course code, course name, number of credits for a course and other scheme related information, do visit full semester subjects post given below.

For Textile Technology 2nd Sem scheme and its subjects, do visit TT 2nd Sem 2021 regulation scheme. The detailed syllabus of engineering graphics is as follows.

Engineering Graphics

#### Concepts and Conventions (Not for Examination)

Importance of graphics in engineering applications Use of drafting instruments BIS conventions and specifications Size, layout and folding of drawing sheets Lettering and dimensioning.

#### Unit II

PROJECTION OF POINTS, LINES AND PLANE SURFACE Orthographic projection- principles-Principal planes-First angle projection-projection of points. Projection of straight lines (only First angle projections) inclined to both the principal planes -Determination of true lengths and true inclinations by rotating line method and traces. Projection of planes (polygonal and circular surfaces) inclined to both the principal planes by rotating object method.

#### Unit IV

PROJECTION OF SECTIONED SOLIDS AND DEVELOPMENT OF SURFACES Sectioning of above solids in simple vertical position when the cutting plane is inclined to the one of the principal planes and perpendicular to the other obtaining true shape of section. Development of lateral surfaces of simple and sectioned solids Prisms, pyramids cylinders and cones. Practicing three dimensional modeling of simple objects by CAD Software(Not for examination)

#### Course Outcomes:

On successful completion of this course, the student will be able to

• Use BIS conventions and specifications for engineering drawing.
• Construct the conic curves, involutes and cycloid.
• Solve practical problems involving projection of lines.
• Draw the orthographic, isometric and perspective projections of simple solids.
• Draw the development of simple solids.
