Basic Engineering DrawingCourse Code3300007GUJARAT TECHNOLOGICAL UNIVERSITY, AHMEDABAD, GUJARATCOURSE CURRICULUMCourse Title: Basics Engineering Drawing(Code: 3300007)1Diploma Programmes in which this course is offeredAutomobile Engineering,Ceramic Engineering,CivilEngineering, Environment Engineering, Mechanical Engineering,Mechatronics Engineering, Metallurgy Engineering, MiningEngineering, Printing Technology, Textile ManufacturingTechnology, Textile Processing, Transportation EngineeringSemester in which offeredChemical Engineering, Electrical Engineering, FabricationTechnology, Plastic EngineeringSecond SemesterFirst SemesterRATIONALE:Engineering drawing is an effective language of engineers. It is the foundation block which strengthensthe engineering & technological structure. Moreover, it is the transmitting link between ideas andrealization. It is an attempt to develop fundamental understanding and application of engineering drawing.It covers knowledge & application of drawing instruments & also familiarizes the learner about Bureau ofIndian standards. The curriculum aims at developing the ability to draw and read various drawings, curves& projections.The subject mainly focuses on use of drawing instruments, developing imagination and translating ideas.Developing the sense of drawing sequence and use of drawing instruments effectively yields not onlywith productive preparation of computer aided graphics but also yields with effective industrialapplications ranging from marking to performance of operations.2LIST OF COMPETENCIES:The course content should be taught and implemented with the aim to develop different types ofskills leading to the achievement of the following competencies:i.ii.Prepare engineering drawings manually with given geometrical dimensions using prevailingdrawing standards and drafting instruments. .Visualize the shape of simple object from orthographic views and vise versa.GTU/ NITTTR Bhopal/12Gujarat State

Teacher willassign the problem of particular sheet to be explained toeach batch student. Each student will assess at least one sheet of otherstudents (May be a group of 5-6 students identified byteacher can be taken) and will note down the mistakescommitted by them. Student will also guide the studentsfor correcting the mistakes, if any.06040810--Use both sides of sheet. For example, draw sheet number 2 on back side of sheet number1, 4 on back of 3, and likewise.Theory & practice should be in first angle projections and IS codes should be followedwherever applicable.The dimensions of line, axes, distances, angle, side of polygon, diameter, etc. must be variedfor each student in batch so that each student will have same problems, but with differentdimensions.The sketchbook has to contain data of all problems, solutions of all problems and studentactivities performed. Students’ activities are compulsory to be performed.GTU/ NITTTR Bhopal/12Gujarat State
