Course Title : Engineering Graphics

Coordinator :Prof. A B AMALE

Subject Teacher :- Prof N SUNHERIYA

Course Description:

Introduction to AutoCAD commands, simple drawings, orthographic projections, projections of points, lines, planes and solids. Pictorial drawings, Techniques for auxiliary projections, spatial geometry. Geometric solids and sections. Development and intersection of surfaces, sectioning.

Scope and objective of the course:

Engineering Graphics is the primary medium for development and communicating design concepts. Through this course the students are trained in Engineering Graphics concepts with the use of AutoCAD. The latest ISI code of practice is followed. Computerized drafting is an upcoming technology and provides accurate and easily modifiable graphics entities, easy data storage and retrieval facility and enhances creativity.

Syllabus:

Unit.1

Introduction to AutoCAD- Basic commands.

Unit.2

Theory of Projections- Theory Techniques, first angle and third angle projections, multi view drawing from pictorial views. Theory of isometric and oblique drawing, construction of isometric and oblique from orthographic. Need of primary and secondary auxiliary views, true shapes. Identification and drawing of missing lines and view in orthographic projections.

Unit.3

Spatial Geometry- projection of points, lines, true lengths, inclinations, shortest distance, planes.

Unit.4

Geometrical solids and sections- construction of right , regular, oblique solids, section planes and sectional views.

Unit.5

Development of surfaces- radial line, parallel line and reverse development.

Unit.6

Intersection of surfaces- intersections between: line- plane, plane- plane, line-solid, solid-solid.

(F) Online Examination Conduct

  • Upload the question paper before batch starts in case of Mid Term Test through network. In case of comprehensive examination only ortho grid file will be uploaded on client machines.
  • Ask them to open the uploaded file and SAVE it as his ID number. [e.g. 10MEGMSEI-01].
  • Take students in before 15 minutes. Let them sit.
  • Distribute the question paper. Start the exam.
  • Pass on the hard copy format of evaluation sheet to students to enter ID | Name | Work Station No.
  • If possible the exam should be on UPS / generator power supply. Otherwise ask students to SAVE the file every 2-3 minutes with a simple command Ctrl + S.
  • Once the exam starts, discuss the evaluation scheme patiently for 10-15 minutes.
  • Course coordinator will not involve him for evaluation. His role is silent observer as well as ‘Rechecker’.
  • Once the time is over, announce to SAVE & EXIT. DO NOT use QUIT. Command. Ask them to sit silently. Evaluator will come to student for evaluation with given evaluation sheet.
  • Normally 8-9 students can be evaluated in 30 minutes
  • Model solution key is shown to students and start evaluation. No discussion on model solution and evaluation scheme.
  • Once the evaluation is over then evaluator should come out of AutoCAD with EXIT command. Ask student to leave the exam hall.
  • By any chance if students would like to apply for recheck then he should sit. He can raise his hand so that the course coordinator can come to him for recheck.
