Setsquares are made of transparent celluloid or acrylic and may also contain French curves.Ī procircle is circular in shape. Setsquares are used to draw parallel and perpendicular lines. Plain dividers are used to divide straight or curved lines into a prescribed number of equal parts, for transferring dimensions and for setting of distances from a scale to drawings.īow dividers are used to hold precise distances for dividing or transferring.Īn inking pen is used to draw straight or curved lines in tracing ink.Ī lead case is used to store pencil leads.Ī screwdriver is used to tune the screws in the instruments. For drawing circles of more than 100 mm diameter, a lengthening bar is used.īow compasses are used for drawing small circles up to 25 mm diameter.ĭividers are used in conjunction with scales. Large compasses are used to draw circles up to 100 mm diameter. Compasses are used in conjunction with scales (rulers). The instruments in an instrument box are made of nickel coated steel or brass.Ī pair of compasses are used to draw circles and arcs.
There are two essential parts of a T-square, namely the stock and the blade. It can be easily and quickly moved to any location on the drawing sheet without altering the scales.Ī T-square is mainly used together with setsquares for drawing horizontal lines, angles and perpendicular lines.
It combines the functions of a T-square, setsquares, scales and a protractor. The drawing sheet should be tough and strong and its fibers should not disintegrate when an eraser is used on its surface.Ī minidrafter is a device with two scales set at right angles to each other. The ratio of the width of a drawing sheet to its length is 1: !2. The standard sizes of drawing sheets as per BIS (10711-1983) are given in the table. The standard sizes of drawing boards as per BIS (1444-1977) are given in the table. Drawing boards are made of well-seasoned softwood such as Oak or Pine. The D2 or D3 drawing boards are usually used in polytechnics and engineering colleges. Use the lettering and dimensioning techniques in common practice.Draw the layout and title block on a drawing sheet.Classify drawing sheets and the different grades of drawing pencils.Identify various types of drawing instruments and their uses.On completion of the session, you should be able to: In this, the first session, you'll be looking at drawing instruments and the typical accessories used in drawing. An inaccurate drawing may misguide the workman and ultimately affect Engineers must have perfect drawing skills and excellent working knowledge of engineering concepts. Drawings drawn by an engineer for engineering purposes is Engineering Drawing.ĭrawing is the Universal Graphical Language of Engineers, spoken, read and written in its own way. We are pleased to offer this training in our library.A picture is worth saying a thousand words hence drawings are used to visually communicate ideas, thoughts, and designs. By the end of this course, you'll have the skills to create clear, complete drawings that hold up to the most exacting standards. Join the engineering team from Tarkka for this hands-on look at creating engineering drawings for manufacturing, from preparing your template and selecting the right drawing type to choosing and placing views, specifying dimensions, and setting tolerances. For the employer, this course can reduce the time required to train new engineers and decrease the potential for costly mistakes due to poor drawings. For the learner, this course can increase marketability and reduce frustration during the first months of a new career. This course teaches the practical skills needed to independently prepare clear drawings that satisfy industry standards.
MET STANDARD NOTES ENGINEERING GRAPICS TRIAL
New engineers have traditionally had to learn drafting skills on the job, usually by trial and error. Preparing clear, complete engineering drawings is a critical skill for nearly every design engineer.
