Study Notes

Civil Engineering Drawing Practical Course

Course Description: This is a practical course covering engineering drawing.
First Semester: The course covers 15 practical exercises, drawing sheets, objective tests, evaluation/reports, OEL projects, QOBE based results, and viva voce/result.
Drawing Instruments: A variety of instruments are used. Some include: drawing board, drawing sheet, T-square, set squares, protractor, French curves, set of pencils, clinograph, compass, divider, drawing templates, masking tape, eraser, scale, paper pins.
Drawing Papers: Commonly used drawing papers include drawing paper, graph paper, copy paper, bond paper, card stock, glossy paper, matte paper, newsprint, tissue paper, construction paper, watercolor paper, coated paper, tracing paper, as well as water-marked paper.
Paper Sizes: Standard paper sizes like A0, A1, A2, A3, A4, A5, B0, B1, B2, B3, B4, B5, as well as Letter and Legal sizes are included.
Line Types: Various types of lines are used for technical drawing, including continuous thick, continuous thin, chain thin double dashed line, dimension, curved, perpendicular, parallel, railway track, castle, leader or pointer, and hatching lines.
Scales: Engineering drawings use different scales. Full-size drawing are done sometimes and can be reduced or enlarged for different applications.
Polygons and Shapes: The study of polygons including triangles, quadrilaterals, pentagons, hexagons, heptagons, octagons, nonagons, decagons are included.
AutoCAD Software: Use of AutoCAD software is introduced in the course, covering the use of short keys, units and dimensions including using different commands, to draw, and modify.
Projection Of Points: The course involves drawing projections of points in the first and second, third and fourth quadrants using certain techniques to create proper drawings from a 2-D point to a 3-D shape.
Hatches: Various types of engineering hatches are introduced for drawing different components.
Isometric and Perspective View: The course includes drawing isometric and perspective views.
Open-ended Lab: The course includes an open-ended lab assignment.
