TECHNICAL DRAWING
|
| UP Polytechnic/Diploma In Computer Science And Engineering - Technical Drawing (T.D.) 1 Semester Syllabus 2023 - 24 - EdufyHUB 4U |
RATIONALE
The course is aimed at developing basic graphic skills so as to enable them to use these skills in preparation of engineering drawings, their reading and interpretation. Understand the fundamentals of Engineering Drawing. Read and interpret object drawings.
LEARNING OUTCOMES
After undergoing the subject, the students will be able to:
- Draw orthographic projections of different objects.
- Visualize three-dimensional objects and draw Isometric Projections.
- Use the techniques and able to interpret the drawings in the Engineering field.
- Draw exploded views of components & assemblies in preparation of service drawings.
- Draw free-hand sketches of the schematic diagrams of electronic circuits, using standard symbols.
- Prepare drawings from the rough sketches provided and/or enlarge/reduce the given drawings to the desired scale.

INSTRUCTIONAL STRATEGY
Teacher should show model of realia of the component/part whose drawing is to be made. Emphasis should be given on cleanliness, dimensioning, and layout of sheet. Focus should be on proper selection of drawing instruments and their proper use. Students must use H grade pencils for the first few (10 sheets), till they are familiar with the proper thickness of all types of lines. Relevant IT tools to be used to state that 3D solid modeling, which is to be taught at the starting point. Also how 2D views can be obtained from 3D solid modeling to 2D views rather than the conventional method of making the students visualize the 3D view of an object by mentally constructing it from the 2D views.
